1+4*sin(x)=2

1 + 4 \cdot sin (x) = 2

x = 0.25268 \dots + 2 πn, x = π - 0.25268 \dots + 2 πn

Solution steps

1 + 4 sin (x) = 2

Move

1

to the right side

4 sin (x) = 1

Divide both sides by

4

sin (x) = \frac{1}{4}

Apply trig inverse properties

x = arcsin (\frac{1}{4}) + 2 πn, x = π - arcsin (\frac{1}{4}) + 2 πn

Show solutions in decimal form

x = 0.25268 \dots + 2 πn, x = π - 0.25268 \dots + 2 πn

cos (θ) = \frac{7}{8}

sec (x) (2 sin (x) + 1) - 2 (2 sin (x) + 1) = 0

3 sin^{2} (x) + 2 cos (2 x) = 1

1 = sin (x) + 3 cos (x)

1 + sin (x) = 2 cos^{2} (x), 0 \leq x < 5
