I'm trying to find the partial derivative of Q with respect to w0 and then set it equal to 0 and solve for w0. Finding the partial derivative was easy, but once I've got it, I'm having a hard time getting w0 by itself. Here's the original equation:
[tex]
Q(w_{0},w_{1},w_{2},w_{3})=\sum\left(y_{i} - w_{2}\frac{1}{1+e^{x_{i}w_{0}+w_{1}}} - w_{3}\right)^{2}
[/tex]

Q(w_{0},w_{1},w_{2},w_{3})=\sum\left(y_{i} - w_{2}\frac{1}{1+e^{x_{i}w_{0}+w_{1}}} - w_{3}\right)^{2}
