Math Help - Regarding newton raphson method

Hello people!

We are actually trying to solve equations in c# using newton raphson method .

It is working fine for multivariable linear equations .

But there seems to be a problem with non-linear equations .

The values are not converging and are quite random for non-linear equations.

we are using jacobians to solve the multivariable equations.

Any help would be greatly appreciated .

Thankyou

Can you give an example of a non-linear problem where Newton-Raphson fails?
