| The '''butterfly curve''' is a [[Transcendental function|transcendental]] [[plane curve]] discovered by [[Temple H. Fay]]. The curve is given by the following [[parametric equation]]s:
| |
| | |
| :<math>x = \sin(t) \left(e^{\cos(t)} - 2\cos(4t) - \sin^5\left({t \over 12}\right)\right)</math>
| |
| | |
| :<math>y = \cos(t) \left(e^{\cos(t)} - 2\cos(4t) - \sin^5\left({t \over 12}\right)\right)</math>
| |
| | |
| or by the following [[polar equation]]:
| |
| | |
| :<math>r=e^{\cos \theta} - 2 \cos (4 \theta ) + \sin^5\left(\frac{2 \theta - \pi}{24}\right)</math>

The writer's name is Christy. It's not a common factor but what she likes performing is to play domino but she doesn't have the time recently. I've always loved living in Alaska. Office supervising is exactly where her main earnings comes from but she's already utilized for another one.
