Integrating Equations

8-3

Example:

Bessel Function.

The Bessel function of the first kind of order 0 can be expressed as

Find the Bessel function for x–values of 2 and 3.

Enter the expression that defines the integrand's function:

cos (x sin t )

Now integrate this function with respect to t from zero to

π ; x = 2.
