0=3cos(θ)

0 = 3 cos (θ)

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

Solution steps

0 = 3 cos (θ)

Switch sides

3 cos (θ) = 0

Divide both sides by

3

cos (θ) = 0

General solutions for

cos (θ) = 0

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

1 - 3 sin^{2} (x) = cos^{2} (x) - sin^{2} (x)

sin^{2} (θ) - sin (θ) + 1 = cos^{2} (θ)

1 = l cos (x)

tan (2 x) = cos (2 x), 0 \leq x \leq π

5 sin (2 x) = 5 cos (x), 0 \leq x \leq 2 π
