solvefor x,1-2cos(x)=0

solve for

x, 1 - 2 cos (x) = 0

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

Solution steps

1 - 2 cos (x) = 0

Move

1

to the right side

- 2 cos (x) = - 1

Divide both sides by

- 2

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

0 = 1 + sin (θ)

2 cos (2 x) - cos (x) - 1 = 0

tan (x) \cdot tan (2 x) = 1

cos (x) cot (x) - 3 (1 - sin (x)) = 0

18 = \frac{1}{2} \cdot 9 \cdot 5 \cdot sin (θ)
