There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {X}^{3} - 16{x}^{2} + 30x + 400\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = X^{3} - 16x^{2} + 30x + 400\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( X^{3} - 16x^{2} + 30x + 400\right)}{dx}\\=&0 - 16*2x + 30 + 0\\=& - 32x + 30\\ \end{split}\end{equation} \]
