sin(θ)+3=5sin(θ)

sin (θ) + 3 = 5 sin (θ)

θ = 0.84806 \dots + 2 πn, θ = π - 0.84806 \dots + 2 πn

Solution steps

sin (θ) + 3 = 5 sin (θ)

Solve by substitution

sin (θ) = \frac{3}{4}

sin (θ) = \frac{3}{4} : θ = arcsin (\frac{3}{4}) + 2 πn, θ = π - arcsin (\frac{3}{4}) + 2 πn

Combine all the solutions

θ = arcsin (\frac{3}{4}) + 2 πn, θ = π - arcsin (\frac{3}{4}) + 2 πn

Show solutions in decimal form

θ = 0.84806 \dots + 2 πn, θ = π - 0.84806 \dots + 2 πn

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

csc (x) cos^{2} (x) + sin^{2} (x) = csc (x)

0.87 = 5 cos (3 x)

cos (\frac{2 π x}{3}) = \frac{1}{2}

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