1 Answer
They can be determined by looking at the coefficients and their location.
Explanation:
Let's look at this equation:
The
First,
Second,
For example, the period of cosine is
For your specific question,
NOTE: I wanted to mention to be careful when finding the period of tangent, as the normal period of tangent is
