sin(x/2)= 3/5

sin (\frac{x}{2}) = \frac{3}{5}

x = 2 \cdot 0.64350 \dots + 4 πn, x = 2 π - 2 \cdot 0.64350 \dots + 4 πn

Solution steps

sin (\frac{x}{2}) = \frac{3}{5}

Apply trig inverse properties

\frac{x}{2} = arcsin (\frac{3}{5}) + 2 πn, \frac{x}{2} = π - arcsin (\frac{3}{5}) + 2 πn

Solve

\frac{x}{2} = arcsin (\frac{3}{5}) + 2 πn : x = 2 arcsin (\frac{3}{5}) + 4 πn

Solve

\frac{x}{2} = π - arcsin (\frac{3}{5}) + 2 πn : x = 2 π - 2 arcsin (\frac{3}{5}) + 4 πn

x = 2 arcsin (\frac{3}{5}) + 4 πn, x = 2 π - 2 arcsin (\frac{3}{5}) + 4 πn

Show solutions in decimal form

x = 2 \cdot 0.64350 \dots + 4 πn, x = 2 π - 2 \cdot 0.64350 \dots + 4 πn

16 cos^{2} (x) - 8 = 0

2 sin (4 θ) = 0

θ, 4 sin^{2} (\frac{θ}{2}) + 8 cos (\frac{θ}{2}) - 7 = 0

2 sin^{2} (x) - sin (x) = 0, 0 \leq x \leq 2 π

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