1+3sin(x)=2

1 + 3 sin (x) = 2

x = 0.33983 \dots + 2 πn, x = π - 0.33983 \dots + 2 πn

Solution steps

1 + 3 sin (x) = 2

Move

1

to the right side

3 sin (x) = 1

Divide both sides by

3

sin (x) = \frac{1}{3}

Apply trig inverse properties

x = arcsin (\frac{1}{3}) + 2 πn, x = π - arcsin (\frac{1}{3}) + 2 πn

Show solutions in decimal form

x = 0.33983 \dots + 2 πn, x = π - 0.33983 \dots + 2 πn

cos (\frac{x}{2} + \frac{π}{3}) = \frac{1}{2}

sinh (x) = \frac{2}{2}

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

- 2 sin (2 x) sin (x) = sin (2 x)

2 sin (θ) - 2 = 0, 0 \leq θ \leq 2 π
