Herr: 2 x Sjöstrand flyttas upp, 2020-12-10 20:30 Sin (2x) = 2 Sin (x) Cos (x) — 1 How, from the formula Sin (a+b) = Sin (a) Cos (b) + Cos (a) Sin (b) — 2 Sin (2x) can be written as Sin (x+x) and substitute in equation 2 I.e. a=x and b=x and solving you get the required equation (equation 1). The trigonometric formulas like Sin2x, Cos 2x, Tan 2x are popular as double angle formulae, because they have double angles in their trigonometric functions.
