There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (x - 1)e^{x} - ax*62 + b\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = xe^{x} - e^{x} - 62ax + b\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( xe^{x} - e^{x} - 62ax + b\right)}{dx}\\=&e^{x} + xe^{x} - e^{x} - 62a + 0\\=&xe^{x} - 62a\\ \end{split}\end{equation} \]
