5sin(θ)-2=0

5 sin (θ) - 2 = 0

θ = 0.41151 \dots + 2 πn, θ = π - 0.41151 \dots + 2 πn

Solution steps

5 sin (θ) - 2 = 0

Move

2

to the right side

5 sin (θ) = 2

Divide both sides by

5

sin (θ) = \frac{2}{5}

Apply trig inverse properties

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

Show solutions in decimal form

θ = 0.41151 \dots + 2 πn, θ = π - 0.41151 \dots + 2 πn

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

- 4 cos (5 x) + 1 = 1

- 5 sin (x) = - 2 cos^{2} (x) + 4

6 sin^{2} (θ) - 13 sin (θ) + 7 = 0

sin (x) = 0.1
