All the art that I make involves tons of math. The website that helps me plan my art by letting me test the math for the art is Desmos. As you well know, every shape can be described using at least one equation. Some shapes require piecewise constructions, i.e. equations for several curves that intersect at certain points. I will always use a computer, Desmos, and my knowledge of math to make a drawing. I am unable to draw by hand, because holding a pencil or brush for a long time will give my hand a cramp. Please give me detailed feedback on the equations that describe the curves and lines that comprise my drawings. I look forward to your constructive criticism. Thank you in advance.
