There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (π - x)(π + x)(x - 5)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = π^{2}x - 5π^{2} + 5x^{2} - x^{3}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( π^{2}x - 5π^{2} + 5x^{2} - x^{3}\right)}{dx}\\=&π^{2} + 0 + 5*2x - 3x^{2}\\=&π^{2} + 10x - 3x^{2}\\ \end{split}\end{equation} \]
