sin (90x)=cos x, sin 2a = 2 sin a cos a Sin 7,5° * sin 37,5 ° * sin 52,5° * sin 82,5° = 1/4(2sin 7.5 cos 7.5 * 2 sin37.5 cos 37.t ) = 1/4(sin 15 sin 75) =1/8(2sin 15 cos 15) =1/8(sin 30) =1/16

How do oyu get to sin 15? and sin 75?

sin 52.5 = sin(9037.5) = cos 37.5 sin 82.5 = sin(9087.5) = cos 7.5 2 sin 7.5 cos 7.5 = sin 15 same for sin 75
