That's an odd question. To evaluate this function of #theta# we pick a value for #theta# and substitute it into the expression and work out the arithmetic and trig functions and report the answer.


Perhaps you mean how do we simplify this? We'll, we could expand it with the difference angle formula and the quadruple angle formula, but this way is about as simple as it will get.
