sin(θ)=-4/5

sin (θ) = - \frac{4}{5}

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

Solution steps

sin (θ) = - \frac{4}{5}

Apply trig inverse properties

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

Show solutions in decimal form

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

arcsin (\frac{2}{2})

cot (\frac{5 π}{3})

sin (x) + cos (x) = 1
