csc(θ)=-5/4

csc (θ) = - \frac{5}{4}

θ = - 0.92729 \dots + 2 πn, θ = π + 0.92729 \dots + 2 πn

Solution steps

csc (θ) = - \frac{5}{4}

Apply trig inverse properties

θ = arccsc (- \frac{5}{4}) + 2 πn, θ = π + arccsc (\frac{5}{4}) + 2 πn

Show solutions in decimal form

θ = - 0.92729 \dots + 2 πn, θ = π + 0.92729 \dots + 2 πn

2 - sec^{2} (x) = 0

4 sin (θ) - 22 = 0

sec (θ) = \frac{2}{3}

3 cos (2 θ) - 5 sin (θ) - 9 = - 5

tan (x) = 1, 0 \leq x \leq 2 π
