sin(a)= 1/(sqrt(2))

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

a = \frac{π}{4} + 2 πn, a = \frac{3 π}{4} + 2 πn

Solution steps

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

Simplify

\frac{1}{2} : \frac{2}{2}

\frac{1}{2}

Multiply by the conjugate

\frac{2}{2}

= \frac{1 \cdot 2}{2 2}

1 \cdot 2 = 2

22 = 2

22

Apply radical rule:

a a = a

22 = 2

= 2

= \frac{2}{2}

sin (a) = \frac{2}{2}

a = \frac{π}{4} + 2 πn, a = \frac{3 π}{4} + 2 πn

a = \frac{π}{4} + 2 πn, a = \frac{3 π}{4} + 2 πn
