Define:
f(theta) = sin(theta) = -2/3
f(-theta) = sin(-theta) = -sin(theta) = -(-2/3) = 2/3

If Sin theta = -2/3 find Sin of (-theta)
----------
Formula: sin(x)=-sin(-x)
Therefore If sin theta = -2/3,
sin(-theta)= - sin theta = 2/3

Hi Sarah,
sin theta is an odd, so you're right,
if sin(theta)=-2/3, then sin(-theta)=2/3
Keep up the good work!
Happy Calculating!!!
