I have a complex math problem that needs solving in my research project that I don’t have the time to solve.
It will need calculus and differentiation skills. Let me know if you are interested. For: $f(w, b) = \frac{1}{m}\sum_{i = 1}^{m}\frac{\lvert w^{2}x^{(i)}-w(y^{(i)}-b)\rvert}{cos(tan^{-1}(\frac{y_o^{(i)}}{x_o^{(i)}}))}$ And: $\frac{y_o^{(i)}}{x_o^{(i)}} = \frac{2w^{2}b -wx^{(i)}+ y^{(i)} + b}{w^2x^{(i)} - w(y^{(i)} - b)}$ Solve $\frac{\partial{f(w, b)}}{\partial w \partial b} = 0$ For the variables w and b. $x^{(i)} \text{ and } y^{(i)}$ are each values from one of two different sets of $m$ real numbers from $i = 1 \text{ to } i = m$. -- You received this message because you are subscribed to the Google Groups "sympy" group.
