2-4cos(x)=0

2 - 4 cos (x) = 0

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

Solution steps

2 - 4 cos (x) = 0

Move

2

to the right side

- 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

csc (2 x) - 4 = 0

8 cos (2 x) = 42

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

tan (x) = π

sinh (x) = \frac{5}{12}
