I'm not clear what your instructor meant by his definition of positive and negative angles, but it would seem like it should have been negative.<BR /><BR />TTFN,<BR />Eden</BODY></HTML>Sat, 04 Oct 2003 07:00:00 GMThttps://community.ptc.com/t5/PTC-Mathcad/PHYSICS-PROBLEM/m-p/378154#M148364IRstuff2003-10-04T07:00:00Z
