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