There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {x}^{4} - \frac{40{x}^{3}}{3} + 48{x}^{2}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{4} - \frac{40}{3}x^{3} + 48x^{2}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x^{4} - \frac{40}{3}x^{3} + 48x^{2}\right)}{dx}\\=&4x^{3} - \frac{40}{3}*3x^{2} + 48*2x\\=&4x^{3} - 40x^{2} + 96x\\ \end{split}\end{equation} \]
