sin(2x)cos(x)+cos(2x)sin(x)=0

sin (2 x) cos (x) + cos (2 x) sin (x) = 0

x = \frac{2 πn}{3}, x = \frac{π}{3} + \frac{2 πn}{3}

Solution steps

sin (2 x) cos (x) + cos (2 x) sin (x) = 0

Rewrite using trig identities

sin (2 x + x) = 0

General solutions for

sin (2 x + x) = 0

2 x + x = 0 + 2 πn, 2 x + x = π + 2 πn

Solve

2 x + x = 0 + 2 πn : x = \frac{2 πn}{3}

Solve

2 x + x = π + 2 πn : x = \frac{π}{3} + \frac{2 πn}{3}

x = \frac{2 πn}{3}, x = \frac{π}{3} + \frac{2 πn}{3}

- 10 sin (θ) + 2 = 2

cot (u) - csc (u) = \frac{sin ( u )}{1 + cos ( u )}

sin (x) = \frac{5}{3}

sin (θ) = \frac{3}{4}

2 cos (2 θ) - 1 = 0, 0 \leq θ \leq 2 π
