sin(θ)= 5/8

sin (θ) = \frac{5}{8}

θ = 0.67513 \dots + 2 πn, θ = π - 0.67513 \dots + 2 πn

Solution steps

sin (θ) = \frac{5}{8}

Apply trig inverse properties

θ = arcsin (\frac{5}{8}) + 2 πn, θ = π - arcsin (\frac{5}{8}) + 2 πn

Show solutions in decimal form

θ = 0.67513 \dots + 2 πn, θ = π - 0.67513 \dots + 2 πn

arctan (2 x) + arctan (x) = \frac{π}{4}

tan (a) = 1

cos (2 θ) = 2, cos^{2} (θ) - 1 = 2, (- \frac{3}{5})^{2} - 1 = - \frac{7}{25}

2 sin (2 θ) = 1, 0 \leq θ \leq 2 π

2 cos^{2} (x) - 3 sin (x) = 3
