Console throwing "cos is not defined", "sin is not defined" when i try to use sin, cos functions.

var r = 160; var theta = 0; var xvals = []; var yvals = []; while (theta <= 360) {var x = rcos(theta); var y = rsin(theta); xvals.push(x); yvals.push(y); theta += 4;}

Any idea what's up?

It's hard to read since your post is messed up! /:)
But I can't see any * multiplication operator between variable r and those aforementioned functions? :-&

It's taking the multiply signs as markup which is why some of the text is in italics

var r = 160;
var theta = 0;
var xvals = [];
var yvals = [];
while (theta <= 360) {
  var x = r*cos(theta); 
  var y = r*sin(theta); 
  xvals.push(x); 
  yvals.push(y); 
  theta += 4;
}

Are you using instance mode? Then you need to reference p5: p5.cos

Though you could also directly reference the JS method with: Math.cos
