Question

what is the answer for sin (3π-theta)​

Answer 1

Answer:

sin x

Step-by-step explanation:

sin(2pi + x) = sin x

sin(3π-x) = sin(π-x) = -sin(-x) = sinx

Answer 2

To find the value of sin(3π-∅)

We know that,

π=180

Substituting,

→sin[3(180)-∅]

→sin[540-∅]

→sin(180-∅)

This value is in third quadrant,so sine function would be negative

→ -sin180
