Why use numerical methods?

f(x) is a very highly complicated, like non-linear with multiple dimensions. So its first-order derivative cannot be expressed or calculated analytically. For example the function as follows:

e^{x^{2}}-lnx = 0

Now we need the help of numerical methods to solve the problem.
