Re: Help for a basic problem


write a+bi in polar form as   r*exp(I*theta).  Then the cube roots
are easily expressed in polar form too.

If you don't know about polar form, learn about it.

Can I get a symbolic formula of x, while x satisfies a complex equation, x^3 = a+b*i, where a and b are real-valued variables?

I was trying to figure it out using x = R_x+I_x*i, but it turns out to be a very complex equation.

If no analytical solution is available, how can I get it, by numerical method?

Thanks
