0=2cos(x)

0 = 2 cos (x)

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

Solution steps

0 = 2 cos (x)

Switch sides

2 cos (x) = 0

Divide both sides by

2

cos (x) = 0

General solutions for

cos (x) = 0

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

\frac{cos ( x )}{cos ( x )} = \frac{cos ( x )}{1 + sin ( x )}

- 2 cos (θ) - 3 = 0

4 cos^{2} (2 x) = 1

sec (x) = - 4.5973

2 cos (9 x) = 2 - 2 cos (9 x)
