cos(x)=-3/(2sqrt(3))

cos (x) = - \frac{3}{2 3}

x = \frac{5 π}{6} + 2 πn, x = \frac{7 π}{6} + 2 πn

Solution steps

cos (x) = - \frac{3}{2 3}

Simplify

- \frac{3}{2 3} : - \frac{3}{2}

General solutions for

cos (x) = - \frac{3}{2}

x = \frac{5 π}{6} + 2 πn, x = \frac{7 π}{6} + 2 πn

sec^{2} (x) - 6 sec (x) = 16

cos^{2} (θ) + sin^{2} (θ) = 4

6 arccos (x) - 3 π = 3 arccos (x)

3 sin (2 x) = sin (x)

cos (b) = \frac{12}{37}
