Prompts for value of X.

x = 2. Starts integrating; calculates result for

∫0π f (t)

The final result for J0 (2).

Now calculate J0(3) with the same limits of integration. You must re-specify the limits of integration (0, π) since they were pushed off the stack by the subsequent division by π.

￿Example: Sine Integral.

x = 3. Starts integrating and calculates the result for

∫0π f (t) .

The final result for

J0(3).

Certain problems in communications theory (for example, pulse transmission through idealized networks) require calculating an integral (sometimes called the sine integral) of the form

Si	(t) = ∫ t	(	sin x	)dx
