There are 1 questions in this calculation: for each question, the 1 derivative of m is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{{(y - wx - b)}^{2}m}{2}\ with\ respect\ to\ m：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{1}{2}y^{2}m - ywxm - ybm + \frac{1}{2}w^{2}x^{2}m + wxbm + \frac{1}{2}b^{2}m\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{1}{2}y^{2}m - ywxm - ybm + \frac{1}{2}w^{2}x^{2}m + wxbm + \frac{1}{2}b^{2}m\right)}{dm}\\=&\frac{1}{2}y^{2} - ywx - yb + \frac{1}{2}w^{2}x^{2} + wxb + \frac{1}{2}b^{2}\\=& - ywx - yb + \frac{y^{2}}{2} + wxb + \frac{w^{2}x^{2}}{2} + \frac{b^{2}}{2}\\ \end{split}\end{equation} \]
