sin(x)= 4/5

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

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

Solution steps

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

4 sin^{2} (θ) = 3 cos^{2} (θ), 0^{\circ} < θ < 36 0^{\circ}

2 sin (x) - 2 = 0

tan (θ) = \frac{1}{2}

sin^{2} (x) + cos (x) + 1 = 0

2 cos (2 x) = 0
