Question

The question asks for the exact value of the trigonometric function at the given real number:

\sin (\frac{3 π}{4})

Answer 1

Trigonometric formula:

\sin (π - θ) = \sin θ

Solving the given trigonometric function.

\sin (\frac{3 π}{4})

= \sin (π - \frac{π}{4})

= \sin (\frac{π}{4}) {,^{'} \sin (π - θ) = \sin θ}

= \frac{1}{\sqrt{2}}

The value of given trigonometric function is shown below.

\sin (\frac{3 π}{4}) = \frac{1}{\sqrt{2}}
