cos^3(x)=0

cos^{3} (x) = 0

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

Solution steps

cos^{3} (x) = 0

Apply rule

x^{n} = 0 \Rightarrow x = 0

cos (x) = 0

General solutions for

cos (x) = 0

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

2 cos^{2} (x) + 3 cos (x) = 2

sin (x) cos (x) = 1

csc^{2} (x) = 2

6 sec^{2} (θ) tan (θ) = 8 tan (θ)

1 + cos (x) = 1 - sin (x)
