However, I'd really like to manipulate this curve (stretch/compress, rotate, reflect), as well as other shapes in general. Is there a simple way to do this, possibly store the shape in a variable then apply transformations? Also, how would I go about drawing something like a parabola, or a sine wave? I imagine trying to create them using the same formula for the curve above would prove too tedious.
