Oh, I see, my mistake. Thanks!

OK, so I have a work around here:
from sympy.physics import units as u
class MyVars:
def __init__(self):
'''create a dict of units of interest'''
self.my_units = {}
self.my_units[u.V] = 'V'
self.my_units[u.W] = 'W'
self.my_units[u.A] = 'A'
self.
Are you using SymPy at all here or just mpmath? If it's just mpmath, you
may have better luck on the mpmath mailing list
https://groups.google.com/forum/#!forum/mpmath.

coefficients.
Also note that exp(a*x) != exp(x)**a in general (take x = 2*pi*I and a =
1/2). It should be true if a is an integer, though (but subs doesn't handle
it if you set a = Symbol('a', integer=True)).

Hi,
Thanks for the workaround, but
subs doesn't work here:
>>> sin(exp(a*x)).subs({exp(x): x})
>>> sin(exp(a*x))
Best,

xreplace only does exact structural replacement (the "x" stands for
"exact"). To get mathematical replacement, use subs:
>>> print(exp(5*x).subs(exp(x), sin(x)))
sin(x)**5

Sorry if this ends up being a re-post, I submitted a similar question and I
do not think it went through.
I am working on a project that uses a statistical modelling program whose
output is a linear regression model. THe program has a unique way of
representing various well know equations such a
THe project I am currently working on creates statistical models and
provides the linear regression model as an equation.
It has some package centric ways for defining polynomials and other
functions, for instance:
68.1223e-02*VB_POLY(var_to_use,0.79425485,0.0074458634,-3.659e-05)

I am also Interested in getting the solution for this.
