We aren't here to do your homework for you or to sift through your
bugs. Learn to use your debugger, and ask a specific question related
to the standard C++ language, if you have one.

You have an error on line 42.

When I first saw your answer I thought you were being glib/funny. Then
I looked at line 42.

Are you serious? I *was* being glib.

Line 42 appears to be fine:
POV[0][0]=cos(ugA);

Perhaps you're referring to line 41 which uses an undefined symbol
(or, to be more practical, a symbol that some implementations
define in contravention of the C++ standard)
