Calculates the sin of any number up to 17-20 decimal digits unless it is something that requires less than that like sin(30)=0.5 anyway this is the math function sin which is short for sine so please don't report me. Making cosin(short for cosine) calculator next! P.S. The code for this is extended because of drawing the triangle for an image a efficient version would be not using a drawing like this one : https://scratch.mit.edu/projects/1205022001/
