Absolute value removal

[brombo]

Is there a simple way of removing all absolute values from an expression.  For example if the expression is (Abs(sin(w))/cos(w)) + Abs(w) return (sin(w)/cos(w)) + w.

Hi brombo,

The simplest thing, I can think of as of now:

In [23]: a = (Abs(sin(w))/cos(w)) + Abs(w)

In [24]: S(str(a).replace('Abs', ''))

Out[24]: w + sin(w)/cos(w)

Wouldn't it be better to use

a = Abs(sin(w))/cos(w) + Abs(w)
a.replace(Abs, Id)

rather than deal with strings?

Best,

Renato

Yes, that is certainly better, I couldn't recall this, earlier.

Thanks!
