solvefor x,2cos(2x)=0

solve for

x, 2 cos (2 x) = 0

x = \frac{π}{4} + πn, x = \frac{3 π}{4} + πn

Solution steps

2 cos (2 x) = 0

Divide both sides by

2

cos (2 x) = 0

General solutions for

cos (2 x) = 0

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

Solve

2 x = \frac{π}{2} + 2 πn : x = \frac{π}{4} + πn

Solve

2 x = \frac{3 π}{2} + 2 πn : x = \frac{3 π}{4} + πn

x = \frac{π}{4} + πn, x = \frac{3 π}{4} + πn

tan (2 θ) + tan (2 θ) sin (2 θ) = 0

3 cot (\frac{1}{4} x) = 3

4 sin (x) - cos (2 x) = 1

2 sin^{2} (t) - 3 sin (t) + 1 = 0

5 sin (x) = 0
