prove sin x pi 2 cosx There are 2 ways 1 Use trig identity sin a b sin a cos b sin b cos a In this case sin x pi 2 sin x cos pi 2 sin pi 2 cos x Because cos pi 2 0 and sin
For the true proof you need to use matrice but this is acceptable sin a b sin a cos b cos a sin b sin pi 2 x sin pi 2 cos x cos pi 2 sin Prove sin x pi 2 cos x Using sin a b sin a cos b cos a sin b sin x pi 2 sin x cos pi 2 cos x sin pi 2 0 cos x
