Question

trigonometry full formulae ​

Answer 1

Step-by-step explanation:

sin (π/2 – x) = cos x cos (π/2 – x) = sin x

sin (π/2 + x) = cos x cos (π/2 + x) = – sin x

sin (3π/2 – x) = – cos x cos (3π/2 – x) = – sin x

sin (3π/2 + x) = – cos x cos (3π/2 + x) = sin x

sin (π – x) = sin x cos (π – x) = – cos x
