I was wondering if anyone knew of a procedure or patch for Newton's method with two variables. I checked maple help and there only seemed to be Newton's method for one variable.

It's for root finding when you have two functions, each with one or two variables; it involves a jacobian matrix.

I'm running Maple 13 btw.

How would I plot the following complex function?

f(z) = z² , Domain = {z = x + iy | x < 0 and y > 0}

How would I graph this circle, in the complex plane, in Maple 12:

abs(z - 2) = 2?
