If x is a real number not divisible by , then for all integers n 1, sin x + sin 3x + sin

Chapter 5, Problem 18

(choose chapter or problem)

If x is a real number not divisible by π, then for all integers n ≥ 1,

\(\sin x+\sin 3 x+\sin 5 x+\cdots+\sin (2 n-1) x=\frac{1-\cos 2 n x}{2 \sin x}\).

Text Transcription:

sin x+ sin 3 x + sin 5 x + cdots + sin (2 n-1) x = 1 - cos 2 n x / 2 sin x
