csc(θ)=-7/3

csc (θ) = - \frac{7}{3}

θ = - 0.44291 \dots + 2 πn, θ = π + 0.44291 \dots + 2 πn

Solution steps

csc (θ) = - \frac{7}{3}

Apply trig inverse properties

θ = arccsc (- \frac{7}{3}) + 2 πn, θ = π + arccsc (\frac{7}{3}) + 2 πn

Show solutions in decimal form

θ = - 0.44291 \dots + 2 πn, θ = π + 0.44291 \dots + 2 πn

sin (θ) = \frac{5}{8}

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
