Note that the image below is only for x in Q1 (the first quadrant). If you wish you should be able to draw it with x in any quadrant. Definition of sin(x) (side opposite angle x)//(hypotenuse) Definition of cos(90^@ -x) (side adjacent to angle (90^@-x))//(hypotenuse) but (side opposite angle x) = (side adjacent to angle (90^@-x) Therefore sin(x) = cos(90^@ -x) Similarly cos(x) = sin(90^@ - x)
