cos(x)=sqrt(3/4)

cos (x) = \frac{3}{4}

x = \frac{π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

Solution steps

cos (x) = \frac{3}{4}

Simplify

\frac{3}{4} : \frac{3}{2}

General solutions for

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

x = \frac{π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

sin (x) = sin (\frac{x}{2})

sec (x) - 2 = - tan (x) - 3

- 9.81 + 5 (32.17) (\frac{12}{2}) sin (θ) = 0

2 sin^{3} (x) - sin^{2} (x) - 2 sin (x) + 1 = 0

2 sin (x) = - 2
