cos(x)=0,-pi<= x<= pi

cos (x) = 0, - π \leq x \leq π

x = \frac{π}{2}, x = - \frac{π}{2}

Solution steps

cos (x) = 0, - π \leq x \leq π

General solutions for

cos (x) = 0

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

Solutions for the range

- π \leq x \leq π

x = \frac{π}{2}, x = - \frac{π}{2}

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

sin (θ) = - \frac{4}{5}, \frac{7 π}{2} \leq θ < 4 π, cos (2 θ)

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

- 8 sin (θ) = - 3

sin (x) + 1 = 1
