cos(x)= 5/10

cos (x) = \frac{5}{10}

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

Solution steps

cos (x) = \frac{5}{10}

Cancel the common factor:

5

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

cos^{2} (x) + 9 cos (x) + 18 = 0

sin (\frac{8 π}{23}) = sin (x)

- 2 sin (x) - 4 cos (2 x) = 0

sin (x) + 3 cos (x) = 0

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