How do you find the exact value of sin (pi/ 3)?

We know that pi = 180 degrees

π/3= 120

sin (π/3)= sin120

Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value.

sin 120= sin (90° +30°) = cos 30°

It means that sin 120° = cos 30°

We know that the value of cos 30 degrees is √3/2.

Therefore, sin 120° = √3/2.

sin (π/3)= √3/2
