There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ h - (2h{(a - x)}^{2}){\frac{1}{a}}^{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{4hx}{a} - \frac{2hx^{2}}{a^{2}} - h\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{4hx}{a} - \frac{2hx^{2}}{a^{2}} - h\right)}{dx}\\=&\frac{4h}{a} - \frac{2h*2x}{a^{2}} + 0\\=& - \frac{4hx}{a^{2}} + \frac{4h}{a}\\ \end{split}\end{equation} \]
