where T = 2 is the period. The value of T can be stored using:

Typing the first integral above in the Equation Writer, selecting the entire

expression, and using @EVAL@, will produce the following:

Recall the e

= cos(nπ) + i⋅sin(nπ) = (-1)

. Performing this substitution in the

result above we have:
