cos(3x-pi/8)=(sqrt(2))/2

cos (3 x - \frac{π}{8}) = \frac{2}{2}

x = \frac{2 πn}{3} + \frac{π}{8}, x = \frac{2 πn}{3} + \frac{5 π}{8}

Solution steps

cos (3 x - \frac{π}{8}) = \frac{2}{2}

General solutions for

cos (3 x - \frac{π}{8}) = \frac{2}{2}

3 x - \frac{π}{8} = \frac{π}{4} + 2 πn, 3 x - \frac{π}{8} = \frac{7 π}{4} + 2 πn

Solve

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

Solve

3 x - \frac{π}{8} = \frac{7 π}{4} + 2 πn : x = \frac{2 πn}{3} + \frac{5 π}{8}

x = \frac{2 πn}{3} + \frac{π}{8}, x = \frac{2 πn}{3} + \frac{5 π}{8}

5 (1 - cos (θ)) = sin^{2} (θ)

tan (x) - sec (x) = 1

cos^{2} (x) + 2 cos (x) - 2 = 0

- sin (4 x) \cdot 4 = 0

cos (θ) = \frac{5}{6}
