Problem with integral on WP 34s

[lrdheat]

More poor results, this with an endpoint. While the HP 30b unit converted to a WP 34S does fine, the WP 34S app for iPad produces an infinity error as does the WP 34S on the DM 42. Having the 1/0 occur at an endpoint precludes doing the integral in parts.

The integral from 0 to pi for 1/sqrt(1+cos(x)) (radian mode) should be 2*sqrt(2)~=2.8284

The HP 42S does fine as does the Free 42 app on my iPad.

The iPad and DM 42 versions of WP 34S should be used with caution for these types of problems.
