sin(2x)cos(x)=0,0<= x<= 2pi

sin (2 x) cos (x) = 0, 0 \leq x \leq 2 π

x = 0, x = \frac{π}{2}, x = π, x = \frac{3 π}{2}, x = 2 π

Degrees

x = 0^{\circ}, x = 9 0^{\circ}, x = 18 0^{\circ}, x = 27 0^{\circ}, x = 36 0^{\circ}

Solution steps

sin (2 x) cos (x) = 0, 0 \leq x \leq 2 π

Solving each part separately

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

sin (2 x) = 0, 0 \leq x \leq 2 π : x = 0, x = \frac{π}{2}, x = π, x = \frac{3 π}{2}, x = 2 π

sin (2 x) = 0, 0 \leq x \leq 2 π

2 x = 0 + 2 πn, 2 x = π + 2 πn

2 x = 0 + 2 πn, 2 x = π + 2 πn

Solve

2 x = 0 + 2 πn : x = πn

2 x = 0 + 2 πn

0 + 2 πn = 2 πn

2 x = 2 πn

Divide both sides by

2

2 x = 2 πn

Divide both sides by

2

\frac{2 x}{2} = \frac{2 πn}{2}

Simplify

x = πn

x = πn

Solve

2 x = π + 2 πn : x = \frac{π}{2} + πn

2 x = π + 2 πn

Divide both sides by

2

2 x = π + 2 πn

Divide both sides by

2

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

Simplify

x = \frac{π}{2} + πn

x = \frac{π}{2} + πn

x = πn, x = \frac{π}{2} + πn

Solutions for the range

Solutions for the range

0 \leq x \leq 2 π

x = \frac{π}{2}, x = \frac{3 π}{2}

Combine all the solutions

x = 0, x = \frac{π}{2}, x = π, x = \frac{3 π}{2}, x = 2 π

tan (x + π) + 2 sin (x + π) = 0

sin (x) = \frac{3}{2}

cos^{2} (x) = - cos (x)

sin (θ) - 1 = cos (θ)

sin (x) + cos (x) = - 1
