Question

what is the value of sin 210 with full process

Answer 1

sin 210=sin(180-210)=sin-30=-sin30=-1/2

Answer 2

Given,

Sin 210

To find,

Value of sin 210

Solution,

Sin 210 = sin (180 + 30)

= sin (90 x 2 + 30)

The value of sin 90 is 0 and sin 30 is -1/2 so,

= sin (30)

= -1/2

So the value of sin 210 is -1/2
