trigsimp(cos(x)*tan(x)); works for me. Francis From: tk [mailto:tk@...] Sent: 01 August 2013 5:31 pm To: reducealgebradevelopers@... Subject: [Reducealgebradevelopers] Trig Simplifications / Reductions Hello All, I have been trying to work out if two trig expressions are equivalent. After getting tired of trying it manually, it crossed my mind that REDUCE might be able to help here. But even after switching on "trigsimp", the output is still not reduced to its simplest form, i.e. if I enter : a = Cos(x)*Tan(x) I will not get an output line of : a = Sin(x). What do I need to do here to rationalise sums of long trig quotients ? Kind Regards, TK.  Die Sonne scheint noch.  Sophie Scholl (19211943).
