# Solve non linear symbolic equation

Hi, I want to solve a an expression (quiet long one involving trigonometric functions) which has a lot of symbolic parameters (8 to be exact) for x. It takes a lot of time (I didn't get an output after 45 mins). Is there any way for me to speed up things. I am sure my way is inefficient.

This is pretty vague. Likely Maxima was working behind the scenes as well as it could; some things are just really hard to solve. Did you try the `to_poly_solve=True` parameter?

Yes I did try that. I realized that things need not be complicated. So I re-modelled my problem with some approximations and ended up with a simpler equation that sage could handle. But I don't know how to make approximations (like neglect all powers of a variable) and ended up doing that by hand. Is there any way to make sage do the approximations?
