Question: In Exercises 1 and 4, write the function in terms of the sine function by using the identity A cos wt + B sin wt

In Exercises 1 and 4, write the function in terms of the sine function by using the identity
A cos wt + B sin wt = √A2 + B2 sin (wt + arctan A/B). Use a graphing utility to graph both forms of the function. What does the graph imply?
1. f (t) = 3 cos 2t + 3 sin 2t
2. f (t) = 4 cos t + 3 sin t
