go to x (-240) y (([sin v] of (-240)) * (100)) //240 is the leftmost position of the stage
clear //clears a previously drawn wave, if it exists
pen down //draws the first point of the wave
repeat (480) //the width of the stage is 480 x coordinates
pen up //so the movement to the next position is not interfered with an unintended, out-of-place line
change x by (1) //the use of the block
set y to (([sin v] of (x position)) * (100)) //the result is multiplied by "100" to expand the amplitude for visual preference
pen down //creates the mark
