Homework Statement



I know I posted a similar question elsewhere, but the real problem I am having comes from an example I don't quite understand. There is some little math trick in it that I just don't understand.

The example can be seen in the attachment.

Homework Equations



I understand the first step, but some confusion arises during the second step.

The Attempt at a Solution



I know that the "e's" in the numerator can simplify to "sin(wT/2)*2*j, and that sin (x)/x is equal to Sa(x), but in the second step, I do not understand how the coeficient "T" and the denominator came to be.
