4cos(x)=2

4 cos (x) = 2

x = \frac{π}{3} + 2 πn, x = \frac{5 π}{3} + 2 πn

Solution steps

4 cos (x) = 2

Divide both sides by

4

cos (x) = \frac{1}{2}

General solutions for

cos (x) = \frac{1}{2}

x = \frac{π}{3} + 2 πn, x = \frac{5 π}{3} + 2 πn

5 + 2 tan (3 θ + \frac{π}{3}) = 3

3 sec^{2} (x) - 6 = 0, 0 \leq x \leq 2 π

cot^{2} (x) = 1

2 tan (x) - sec^{2} (x) = 0

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