sin(θ)= 9/10

sin (θ) = \frac{9}{10}

θ = 1.11976 \dots + 2 πn, θ = π - 1.11976 \dots + 2 πn

Solution steps

sin (θ) = \frac{9}{10}

Apply trig inverse properties

θ = arcsin (\frac{9}{10}) + 2 πn, θ = π - arcsin (\frac{9}{10}) + 2 πn

Show solutions in decimal form

θ = 1.11976 \dots + 2 πn, θ = π - 1.11976 \dots + 2 πn

2 sec^{2} (x) - tan^{2} (x) = 3

tan (x) - 2 sin (x) = 0

4 sin (2 t) = 4 cos (t)

- 2 sin^{2} (x) + 2 cos (x) + 2 cos^{2} (x) = 0

1 + 2 sin^{2} (t) = - 5 cos (t)
