This creates what is called a sinewave and a cosinewave. It finds the sine and cosine of a forever, increasing number, and creates a line out of it. You may be wondering, why did you make this? because i felt like it
Q: What is a sine? A. The trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse. Q: What is a cosine? A: The trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse
