There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{xx(225 - xx)x}{4}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{225}{4}x^{3} - \frac{1}{4}x^{5}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{225}{4}x^{3} - \frac{1}{4}x^{5}\right)}{dx}\\=&\frac{225}{4}*3x^{2} - \frac{1}{4}*5x^{4}\\=&\frac{675x^{2}}{4} - \frac{5x^{4}}{4}\\ \end{split}\end{equation} \]
