#37. What is the next step when solving the equation sin (2x) - sin (x) = 0​
alina1380 [7]

sin(2<em>x</em>) - sin(<em>x</em>) = 0

Expand the first term using the double angle identity:

2 sin(<em>x</em>) cos(<em>x</em>) - sin(<em>x</em>) = 0

Factor out sin(<em>x</em>) :

sin(<em>x</em>) (2 cos(<em>x</em>) - 1) = 0

This leaves you with 2 cases that can be solved separately:

sin(<em>x</em>) = 0   or   2 cos(<em>x</em>) - 1 = 0

sin(<em>x</em>) = 0   or   cos(<em>x</em>) = 1/2

[<em>x</em> = 2<em>nπ</em>   or   <em>x</em> = <em>π</em> + 2<em>nπ</em>]   or   [<em>x</em> = <em>π</em>/6 + 2<em>nπ</em>   or   <em>x</em> = 5<em>π</em>/6 + 2<em>nπ</em>]

(where <em>n</em> is any integer)
