Hi,
I have the following piece of code :
function('f',x)
function('g',x)
equation1 = (f(x) + g(x) == x^3)
equation2 = (f(x) == x^3)
substitutions = {f: log, g:exp}
Then I would like to substitute variables in the equations :
equation1.substitute(substitutions) -> log(x) + exp(x) = x^3
equation2.substitute(substitutions) -> f(x) = x^3
equation2.substitute(f=log) -> log(x) = x^3
Why is there no substitution in the second line ? How can I be assured
that the substitution has effectively taken place when I substitute
for many functions ?
Thanks,
Pablo
