Press `` to copy this result to the screen. Then, reactivate the Equation
Writer to calculate the second integral defining the coefficient c
n
, namely,
Once again, replacing e in π
= (-1) n , and using e 2in π
= 1, we get:
Press `` to copy this second result to the screen. Now, add ANS(1) and
ANS(2) to get the full expression for c
n
:
Pressing ˜ will place this result in the Equation Writer, where we can simplify
( @SIMP@) it to read:
Once again, replacing e in π
= (-1) n , results in
