5sin(x)=4

5 sin (x) = 4

x = 0.92729 \dots + 2 πn, x = π - 0.92729 \dots + 2 πn

Solution steps

5 sin (x) = 4

Divide both sides by

5

sin (x) = \frac{4}{5}

Apply trig inverse properties

x = arcsin (\frac{4}{5}) + 2 πn, x = π - arcsin (\frac{4}{5}) + 2 πn

Show solutions in decimal form

x = 0.92729 \dots + 2 πn, x = π - 0.92729 \dots + 2 πn

5 sin (x) = 3

sin (x) (2 cos (x) - 3) = 0

cos^{2} (x) + 5 cos (x) = cos (x) - 3

- 9 sin (x) - 9 cos (x) = 0

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