There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{3}{5} + 3 - \frac{3{x}^{2}}{5} + \frac{18x}{3} - 3\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - \frac{3}{5}x^{2} + 6x + \frac{3}{5}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - \frac{3}{5}x^{2} + 6x + \frac{3}{5}\right)}{dx}\\=& - \frac{3}{5}*2x + 6 + 0\\=& - \frac{6x}{5} + 6\\ \end{split}\end{equation} \]
