Persamaan Lingkaran

Persamaan Lingkaran :

Pusat = ( a,b)
Jari-jari = r

Jika bentuk yang dalam kurung dikuadratkan maka.....

Pusat (P) dan jari-jari r :

Catatan :
dalam menentukan persamaan lingkaran sering digunakan rumus 

1. Jarak titik (x₁,_y1) ke titik (_x2,_y2) adalah d maka :





2. Jarak titik (p,q) ke garis Ax + By + C = 0 adalah d maka :

Hubungan Lingkaran dengan Garis Lurus

Persamaan garis y = px + q disubtitusikan ke dalam persamaan lingkaran untuk menggantikan variabel y sehingga diperoleh persamaan kuadrat ax² + bx + c = 0

Hubungan keduanya dapat ditentukan dengan nilai diskriminannya ( D )

• Jika D > 0 ? Persamaan garis berpotongan dengan lingkaran di dua titik
• Jika D =  0 ? Persamaan garis bersinggungan dengan lingkaran
• Jika D < 0 ? Persamaan raris tidak berpotongan/bersinggungan dengan lingkaran

Persamaan Garis Singgung Lingkaran

1. Lingkaran ( x - a )² + ( y - b )² = r² dengan gradien garis singgung m

2. Persamaan garis singgung di titik (p,q) pada :
a. Lingkaran ( x - a )² + ( y - b )² = r² adalah :

b. Lingkaran x² + y² + Ax + By + C = 0 adalah :

Sketsa Persamaan Lingkaran

Seringkali untuk menyelesaikan suatu persamaan lingkaran diperlukan kemampuan untuk menggambarkan sketsanya sehinggga gambaran mengenai persamaan lingkaran tersebut menjadi lebih jelas dan mudah difahami.

Coba perhatikan penyelesaian soal - soal persamaan lingkaran di bawah ini :

Tentukan persamaan lingkaran yang :

a. berpusat di (2,-3) dan melalui titik (5,7)

b. berpusat di (10,5) dan menyinggung sumbu y

c. berpusat di (-1,-2) dan menyinggung garis 4x + 3y + 5 = 0

d. pusatnya pada garis y = x - 3 dan menyinggung sumbu x di titik (5,0)

Jawab :

a. 

Jari-jari lingkaran = r = jarak titik (2,-3) dengan titik (5,7)

sehingga persamaan lingkarannya :

( x - 2 )² + ( y + 3 )² = 109

b.

karena menyinggung sumbu y maka jari-jarinya ( r) = absis (x) pusat lingkarannya = 10

sehingga persamaan lingkarannya :

( x - 10 )² + ( y - 5 )² = 100





c.

r = jarak titik (-1,-2 ) ke garis 4x + 3y + 5 = 0

sehingga persamaan lingkarannya :

( x + 1 )² + ( y + 2 )² = 1

d.

dari sketsa terlihat bahwa titik X pusatnya = titik singgungnya = 5
kemudian dengan memasukkan nilai X = 5 ke persamaan garis y = x - 3 diperoleh nilai Y pusatnya

y = 5 - x = 5 - 3 = 2

sehingga titik pusatnya = (5,2)




karena menyinggung sumbu x maka jari-jarinya ( r) = ordinat (y) pusat lingkarannya = 2

sehingga persamaan lingkarannya :

( x - 5 )² + ( y - 2 )² = 4

Ingrid Cosma fron Rumenia and UK with the Tzachials

Two weeks in Tsachilla My stay in Chiguilpe has been a mixture of adventure, learning, working with the community, and exploring new dimensions. Oral Hygiene talk to school kids The talk was aimed at increasing Oral Hygiene awareness amongst kids studying at the local school. With the fantastic help from one of the dentists in Santo Domingo, Dr Luis Sanchez, who brought instruments from his practice, the talk was followed by a session of removing badly decayed milk teeth for those kids who needed it. The event was generously supported by who promptly donated boxes of toothpaste, toothbrushes, shampoos and conditioners for the kids. Very warm thanks to all who contributed, and I hold high hopes that this little session will have some long term positive effects on the health awareness of the village kids. Medicinal plants There is a wealth of knowledge in the community regarding the curative merits of various plants. Whilst even the ubiquitous yucca and cocoa were interesting to my untrained mind, the herbal bath certainly seemed to have heavenly properties! Yucca plant Cocoa plant Sauna, Tsachilla style Lecture to third year Dental Students at the Colombia University of Santo Domingo Odontologa y Ortodoncia in Inglaterra. The University is small and relatively newly born. There are thirteen students enrolled in the Dental School, who study by night between 6-10, and work in the day to support themselves. Given their gruesome working schedule, and my tentative Spanish skills, I was expecting a peacefully snoring audience and a very quick exit towards my awaiting steaming bath. Surprise! I encountered a very interested audience, eager to learn and understand more. Only managed to get away explaining there?s an awaiting shaman who?ll be sending them bad energy should they ask any more questions! Cockfight, Armadillo, and the little snake One way of spending Saturday afternoon? Well, it seems to be true, an armadillo cannot be held in captivity?Exciting trying to though? An unfortunate visitor? Urusona and ayahuasca In Tsachilla legends, Urusona is a beautiful and brave woman, now represented by a stone in the middle of the river. Given Urusonas strong character, the site is a powerful inspiration and center of energy for Tsachilla ceremonies. The ayahuasca baptism, at night, in Urusonas headquarters, although not for the faint- hearted, made for an eerie experience. Urusona camping site Balancing the forces of nature Shaman in action Urusona offerings The ayahuasca effect And finally?. It?s been a great experience; I?ve made fantastic friends and learned a great deal about so many things, whilst hopefully I left something behind for the community? ?..Hasta luego, Chiguilpe!

Why You Should Try PC Flight Simulator Games

Today PC flight simulator games (also available for Mac) are the best they have ever been. It does not matter if you love to travel from place to place or have a love for everything in aviation, like me.

Now, with ongoing advancement in technology, flight simulators bring with them a level of realism that has not been seen before. Since most modern computers come standard with more advanced powerful graphic cards, simulator developers can now show this new technology they possess to more users.

Most of the good flying simulators today can deliver such things as real world mapping, current weather conditions that is built into the game that matches your local area, airport layouts with so much detail they look true to life and the option where a player can customize 100's of different types of aircraft.

If you want to travel to a far away country that you have never visited before you can jump into your aircraft simulation game and with it using real world mapping, you can take a good view of the area as you fly over it just as if you were a real pilot in a real airplane. Then after visiting some destinations you like, you can make plans to visit them again in the future.

If you are someone that has a love for aviation and flying but you dont like traveling then the realistic features that are provided by modern flight simulator games will surely grip you and keep you entertained for hours.

With 100's of different airplane and helicopter models to choose from and all of them providing the most accurate representation as possible of the flight controls along with the best possible aircraft response you will no doubt develop flying skills or challenge the ones you have and will be playing for hours.

Flight sims using the method called lod or level of detail can contain high quality graphics which will provide gamers with the best realistic flying experience. Using a large variety of backgrounds gamers can choose from where each background contains graphics that look so real they closely resemble what is actually found in real life, its just like you went there in person! This way the beautifully detailed graphics will allow gamers to truely feel they are pilots and will give them the feeling they have ultimate control of the aircrafts they fly. This is even more true if you have a great computer setup with several screens and appropriate flight sim hardware. Only your wallet is the limit here. Check out this awesome setup here:

Most flight simulation games today also have realistic control tower voices where the player can talk to them and get clearance for taking off and landing as well as inflight directions, such features as these keeps the player engaged for hours of fun. This is very handy to learn, especially if you are planning to get a real pilot license one day, like I do.

So if you love aviation and if you love flying all different types of aircraft then flight simulators will be for you, as you will be able to visit different destinations all across the world again and again giving you hours of entertainment from the comfort of your computer and you can do it all without having to have pilot license. But if you want to have a pilot license later on, flight simulator software is a great way to prepare yourself for it.

While this post is more general, in the next posts I will talk more specific about the better flight sim games, that I like. Stay tuned!

backstreet

Ga pernah kebayang si gue bakal punya hubungan backsreet. tapi ini yang gua alamin hampir 2 bulan kebelakang, gue sama dila (nama samaran) itu backstreet..... hufffttttt , kenapa gue backstreet ya jadi awalnya gini.....

Dulu.... dulu banget ini jamannya gua SMA kelas 2, gue deket sama cewe sebut saja kartin (nama samaran). Gue deket sama dia ya cukup lama lah tapi gua ga tembak tembak, nah si kartin ini sahabatan sama dila, kartin sering cerita ke dila tentang gue. kenapa gue ga tembak tembak si kartin? gue juga ga tau pas gue ketemu dia dan ngasih coklat valentine ternyata gue ga ada perasaan sama sekali ke kartin jadi gue perlahan lahan mulai ngejauhin kartin deh. Ya jujur deh disitu gue emang phpin si kartin, ya abis gimana ya kalo ga ada perasaan si emang gitu hufft..... nah disitu si kartin mulai benci gue deh.

1 tahun berselang... gue lulus SMA dan gue meninggalkan cerita cerita lama gue di SMA gua itu, tetapi pas gue lulus dan gue udah masuk masa perkuliahan, gue malah deket sama dila yang ga lain ga bukan adalah sahabatnya si kartin. Awalnya kita cuma temen di twitter tapi karna sesuatu hal gua minta nomer dila dan kita smsan trus kita whatsapp2an.

awalnya sih emang temen dan si dila juga bilang sama gue itu "kita temenan aja ga bisa lebih dit" cukup down dibilang gitu sama doi, tapi gue malah semakin deket sama dia gue pdkt aja hampir 3 bulanan kan lama juga. Tapi masalah yang dulu udah gua lupa soal si karlin selalu dibahas sama dila. bikin bete bikin males, tapi kenapa gue ga mau kehilangan si dila.

sampai akhirnya gue pun jadian sama dila kita saling jujur jujuran sama perasaan kita dan kita saling sayang. dengan syarat hubungan gue ini ga boleh ketauan sama si kartin huffftttt..... sebenernya kalo si dila ngomong baik baik sama kartin gua yakin sih kartin ga bakal marah sama dila, tapi perlu keberanian yang besar ngomong kejujuran yang menyakitkan itu ke sahabat sendiri....

ya apa boleh buat hubungan gue backstreet deh ga banyak orang tau kalo gue ini udah jadian akhirnya sampe gue anniv yang ngucapin cuma amin doang hehehe, yaudah gapapa hubungan itu ga harus orang lain tau yang penting kan kita yang jalanin hubungan itu baik baik :) gue juga ga nyangka sih sebenarnya masalah yang dulu bisa kembali lagi sekarang mungkin ini pelajaran juga buat gue kalo ga boleh phpin cewe :')

sekian

Shining in Your eyes

I see the red lines in your eyes
its' rays pierce the heart and it feels
wonderful ..
I see gray crossing your eyes
forming a flash of swords
that pierce my heart


        My trembling heart says,
               "I love you".
        We sat down overlooking the blue
        lying beneath our are feet
         Welcoming twilight
         on the other end behind the lush foliage


Our steps we leave
while dreaming in the
afternoon carve out Wednesday
evening at the limit of possibilities
I see the shining in your eyes!
