Trig Functions - Not being recognized as solutions

I am trying to set up a script which has a trig function as its solution. I have the correct notation for displaying the question, but I cannot get the latex input to match my desired solution. I have tried pretty much every variation of inputs and am not sure how to get sin theta as the correct input.

solution = “\sin\\theta
content:
when e1.timeSinceSubmit>0
when e1.latex = solution “Correct!”
otherwise "Simplify \sin^{3}\\theta \ +\ \sin\\theta \cos^{2}\\theta"
