cos(x^2)=1

cos (x^{2}) = 1

x = 2 πn, x = - 2 πn

Solution steps

cos (x^{2}) = 1

General solutions for

cos (x^{2}) = 1

x^{2} = 0 + 2 πn

Solve

x^{2} = 0 + 2 πn : x = 2 πn, x = - 2 πn

x = 2 πn, x = - 2 πn

2 sin^{2} (θ) + cos (θ) - 2 = 0

sin^{3} (x) - 0.25 sin (x) = 0

sin^{2} (x) cos (x) = 0

sin (x) - cos (x) = \frac{3}{2}

cos (x) = \frac{1 - cos ( x )}{2}
