sin(θ)=(sqrt(21))/5

sin (θ) = \frac{21}{5}

θ = 1.15927 \dots + 2 πn, θ = π - 1.15927 \dots + 2 πn

Solution steps

sin (θ) = \frac{21}{5}

Apply trig inverse properties

θ = arcsin (\frac{21}{5}) + 2 πn, θ = π - arcsin (\frac{21}{5}) + 2 πn

Show solutions in decimal form

θ = 1.15927 \dots + 2 πn, θ = π - 1.15927 \dots + 2 πn

sin (α) = \frac{3}{5}

x, tan^{2} (x) = 1

x, tan^{2} (x) = 2

x, \frac{p}{q} = sin^{2} (x)

cos (2 x) = 1 - 2 (\frac{3}{5})^{2}
