tan(a/2)= 1/2

tan (\frac{a}{2}) = \frac{1}{2}

a = 2 \cdot 0.46364 \dots + 2 πn

Solution steps

tan (\frac{a}{2}) = \frac{1}{2}

Apply trig inverse properties

\frac{a}{2} = arctan (\frac{1}{2}) + πn

Solve

\frac{a}{2} = arctan (\frac{1}{2}) + πn : a = 2 arctan (\frac{1}{2}) + 2 πn

a = 2 arctan (\frac{1}{2}) + 2 πn

Show solutions in decimal form

a = 2 \cdot 0.46364 \dots + 2 πn

sin (x) = 0.731

sin (x) = 0.766

sin (x) = 0.755

3 tan^{2} (x) - 5 tan (x) + 2 = 0
