2sin(θ)=-sqrt(2),0<= θ<2pi

2 sin (θ) = - 2, 0 \leq θ < 2 π

θ = \frac{5 π}{4}, θ = \frac{7 π}{4}

Solution steps

2 sin (θ) = - 2, 0 \leq θ < 2 π

Divide both sides by

2

sin (θ) = - \frac{2}{2}

General solutions for

sin (θ) = - \frac{2}{2}

θ = \frac{5 π}{4} + 2 πn, θ = \frac{7 π}{4} + 2 πn

Solutions for the range

0 \leq θ < 2 π

θ = \frac{5 π}{4}, θ = \frac{7 π}{4}

y, x = arcsin (y^{2})

cos^{2} (2 x) + cos (2 x) - \frac{3}{4} = 0

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

cos (θ) = \frac{11}{5}

10 cos (θ) = 4 sin^{2} (θ) + 2
