sin(nx) = 2 · cos x · sin((n − 1)x) − sin((n − 2)x). This can be proved by adding formulae for sin(( n − 1) x + x ) and sin(( n − 1) x − x ) . Serving a purpose similar to that of the Chebyshev method, for the tangent we can write:

To do this, multiply equation (i) and (ii). Sin 2x = 2 sin x cos x. Cos 2x = 2 cos2x − 1. 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.

2008-11-06 · sin 2x = 2 tan x / (1 + tan^2 x)-----Expand out cos 2x using the double angle formula as 2 cos^2 x - 1. We know cos = 1 / sec, so, this becomes: (2 / sec^2 x) - 1. We know sec^2 = 1 + tan^2, so: 2 / (1 + tan^2 x) - 1. You can them simplify, as follows, by putting it all over a common denominator: 2 / (1 + tan^2 x) - (1 + tan^2 x) / (1 + tan^2 x

Sin 2x = 2 sin x cos x. Cos 2x = 2 cos2x − 1. 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.

Given that sin(A)= 3/5 and 90 o < A < 180 o, find sin(A/2). Solution: First, notice that the formula for the sine of the half-angle involves not sine, but cosine of the full angle. So we must first find the value of cos(A). To do this we use the Pythagorean identity sin 2 (A) + cos 2 (A) = 1. In this case, we find:

2 cos2(x) = 1 + cos(2x).
