We will follow the following steps: Step 1) Use the Double angle formula. Sin 2x = 2 Sin x Cos x. Step 2) Let’s rearrange it and factorize. 2Sinx Cosx – sinx = 0.

Sin 2x formula

Multiply the above two answers to get the value: sin 2x cos 2x = (2 sin x cos x) (2 cos2x − 1) = 2 cos x (2 sin x cos2 x − sin x) Now, consider equation (i) and (iii), sin 2x = 2 sin x cos x. cos 2x = 1 − 2 sin2x. sin(2X) = 2 sinX cosX cos(2X) = 1 - 2sin 2 X = 2cos 2 X - 1 tan(2X) = 2tanX / [ 1 - tan 2 X ] Multiple Angle Formulas sin(3X) = 3sinX - 4sin 3 X cos(3X) The relation between trigonometric functions of a complex argument and the exponential function is given by Euler’s formula: e iz = cos z + i sin z. From this formula expressions can be obtained for sin x and cos x in terms of the exponential functions of a purely imaginary argument: Se hela listan på matteboken.se cos 2 ⁡ θ + sin 2 ⁡ θ = 1. {\displaystyle \cos ^ {2}\theta +\sin ^ {2}\theta =1.} The other trigonometric functions can be found along the unit circle as. tan ⁡ θ = y B {\displaystyle \tan \theta =y_ {\mathrm {B} }\quad } and.
