3=6cos(x)

3 = 6 cos (x)

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

Solution steps

3 = 6 cos (x)

Switch sides

6 cos (x) = 3

Divide both sides by

6

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

2 cos (a) \cdot sin (2 a) - 1 + 2 sin (2 a) - cos (a) = 0

a, \frac{8 0 ^{2} sin ( 2 a )}{9.8} = 350

tan (A) = \frac{5}{12}, b = 3

tan (2 β) = - \frac{4}{3}

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