The exact value of sin 5π/4 is 0. 0677

<h3>How to find the value</h3>

It is important to note that π = 3. 142

Let's find sin 5π

Substitute the value

sin 5π = sin (5 × 3. 142) = sin 15. 71

= \frac{sin 15. 71}{4}

Find the sine of the number

= \frac{0. 27076}{4}

= 0. 0677

Thus, the exact value of sin 5π/4 is 0. 0677
