Click the green flag and watch the dot mark out a sine and cosine wave. If it's too slow, SWITCH IT TO TURBO!!!!111!!1!1!!!!!one! (shift + green flag)
Click the button in the lower right to change from grid to blank background. I used an idea from a help screen I viewed for the math block. I also used a modified version of the x-y grid that comes with scratch. Green = cosine, blue = sine, red = tangent. If you like, you may use the 'Graph trig function' block, taken that you give credit in this box.
