(cos(x)+3cos(x))/(2+2)=0

\frac{cos ( x ) + 3 cos ( x )}{2 + 2} = 0

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

Solution steps

\frac{cos ( x ) + 3 cos ( x )}{2 + 2} = 0

Simplify

\frac{cos ( x ) + 3 cos ( x )}{2 + 2} : cos (x)

cos (x) = 0

General solutions for

cos (x) = 0

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

3 tan^{3} (x) - tan^{2} (x) - tan (x) - 1 = 0

cos (2 x + 60) = cos (x)

3 tan (x) - 3 cot (x) - 1 = 0

5 sin^{2} (x) + 6 cos (x) - 6 = 0

sin^{2} (x) - sin (x) cos (x) - 6 cos^{2} (x) = 0
