Detlef Mueller wanted Mathematica to express Sec, Csc, ... in terms of Sin, Cos, Tan. You can install my HoldTemporary package posted at http://www.mathsource.com/Content/Enhancements/System/0211-587 Then evaluate the expression below and everything will be formatted the way you want. Needs["Enhancements`HoldTemporary`"]; $PrePrint=HoldTemporary@@( (Hold@@{#/. {Sec[x_]:>1/cos[x],Csc[x_]:>1/sin[x],Cot[x_]:>1/tan[x],Sech[x_]:>1/cosh[x],C sch[x_]:>1/sinh[x]} })/. {cos®Cos,sin®Sin,tan®Tan,cosh®Cosh,sinh®Sinh} )&; ----------- Regards, Ted Ersek Get Mathematica tips, tricks from http://www.verbeia.com/mathematica/tips/Tricks.html
