Question

If 3 tan theta = 3 sin theta then find the value of sin theta

Answer 1

Answer: 0 radians

Explanation: Looking at the unit circle, tan and sin equal each other at 0 radians. Sin(0) = 0 and tan(0) = 0/1 = 0.
Therefore, theta equals 0. Multiplying by 3 does not matter in this case because it is being multiplied by 0. Any number multiplied by 0 is 0.
