7cos(x)=0

7 cos (x) = 0

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

Solution steps

7 cos (x) = 0

Divide both sides by

7

cos (x) = 0

General solutions for

cos (x) = 0

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

sin (θ) = \frac{3 13}{13}, sec (θ)

sin (y) = \frac{1}{2}

3 sin^{2} (x) = 5 sin (x) + 2

sin (x) + cos (x) = 0, - \frac{π}{2} \leq x \leq π

sin (x) = \frac{7}{4}
