2cos^2(x-1)=0

Solution

2 cos^{2} (x - 1) = 0

Solution

x = \frac{π}{2} + 2 πn + 1, x = \frac{3 π}{2} + 2 πn + 1

+1

Solution steps

2 cos^{2} (x - 1) = 0

Divide both sides by

2

cos (x - 1) = 0

General solutions for

cos (x - 1) = 0

x - 1 = \frac{π}{2} + 2 πn, x - 1 = \frac{3 π}{2} + 2 πn

Solve

x - 1 = \frac{π}{2} + 2 πn : x = \frac{π}{2} + 2 πn + 1

Solve

x - 1 = \frac{3 π}{2} + 2 πn : x = \frac{3 π}{2} + 2 πn + 1

x = \frac{π}{2} + 2 πn + 1, x = \frac{3 π}{2} + 2 πn + 1
