Hello,

Here is a pre calculus problem I am having trouble with. The problem is from a review sheet for pre calculus, but I do not recall doing anything like this in my pre calculus class.

(a) Express the function $\displaystyle f(x) = - \sin 2x + \sqrt{3} \cos 2x$ in terms of sine only.

(b) Find the amplitude A, period P, and phase shift B of the function, and graph one complete period.

Any help is greatly appreciated.

Thanks
