This question asks us to basically simplify this expression down to either sine theta, cosine theta, tangent theta, or co -secent theta.

So what i'm going to do is i'm going to start by writing secant theta as 1 over cosine theta, co -saceteta as 1 over sine theta, and then on the bottom, 1, and then plus sine theta over cosine theta.

Okay? so what that means is i'm going to then take and multiply all of this by the common denominator, which is sine theta, cosine, theta.

So i'm going to do that on the top and the bottom, all right? so essentially i'm multiplying by one.

So that result is sine theta, okay, because the cosine theta cancels, plus cosine theta because the sine theta cancels, divided by one becomes sine theta...
