If you want to negate all cos arguments in an expression, you can run subst(expression,cos,x->cos(-x)). Pr Parisse -- that is a big help, thank you. I will keep working on getting *all* sin and cos results to be represented as an equivalent "cos(gamma*t + phi)", but I think that is in the homework stage for me, getting to know the subst() transformation better. |
