update major trigonometric help files and regression tests

Browse Source 
Improved help files for sin, cos, tan, cot, sec, csc.  In case
of tan, cot, sec, csc corrected help file was corrected to
indicate that complex arguments are allowed.  This was a help
file oversight from long ago when those trigonometric functions

Expanded the calc regression test suite test 34dd to test various
real and complex values for sin, cos, tan, cot, sec, csc.
