Prove that sin(θ) + cos(θ)cot(θ)

Our math teacher gave this to us on our most recent test as a bonus:

. . . . .Prove that sin(θ) + cos(θ)cot(θ)

The answer isn't in her key so I was wondering if some of you could lead me to finding the answer. If no one can figure it out I have my math tutor coming tomorrow, so it's not a big deal. Many thanks in advanced.

There is nothing to prove. You have not even made a statement. What is your question?

Perhaps you mean "simplify" rather than "prove" ??

In cases like these I think the best idea is to write everything in terms of sin and cos.

Give that a go. Then get a common denominator, remember the Pythagorean identity and you're pretty much done!
