Answer :

sin 270° = sin 3π/2 = -1, the value of 0 is 270° or 3π/2.

Given,

sin 0 = -1

We have  to find the value of 0.

Lets see the trigonometric table for sin.

  • sin 0 = sin 0 = 0
  • sin 30°= sin π/6 = 1/2
  • sin 45° = sin π/4 = 1/√2
  • sin 60° = sin π/3 = √3/2
  • sin 90° = sin π/2 = 1
  • sin 180° = sin π = 0
  • sin 270° = sin 3π/2 = -1
  • sin 360° = sin 2π = 0

From the above table we get the value of sin 0

The value -1 is for sin 270° which is equal to sin 3π/2

That is,

sin 270° = sin 3π/2 = -1, the value of 0 is 270° or 3π/2.
