0=4cos(4x)

Solution

0 = 4 cos (4 x)

Solution

x = \frac{π}{8} + \frac{πn}{2}, x = \frac{3 π}{8} + \frac{πn}{2}

+1

Solution steps

0 = 4 cos (4 x)

Switch sides

4 cos (4 x) = 0

Divide both sides by

4

cos (4 x) = 0

General solutions for

cos (4 x) = 0

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

Solve

4 x = \frac{π}{2} + 2 πn : x = \frac{π}{8} + \frac{πn}{2}

Solve

4 x = \frac{3 π}{2} + 2 πn : x = \frac{3 π}{8} + \frac{πn}{2}

x = \frac{π}{8} + \frac{πn}{2}, x = \frac{3 π}{8} + \frac{πn}{2}
