There are 1 questions in this calculation: for each question, the 4 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ 4th\ derivative\ of\ function\ (sin(x))*\frac{3}{5}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = \frac{3}{5}sin(x)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{3}{5}sin(x)\right)}{dx}\\=&\frac{3}{5}cos(x)\\=&\frac{3cos(x)}{5}\\\\ &\color{blue}{The\ second\ derivative\ of\ function:} \\&\frac{d\left( \frac{3cos(x)}{5}\right)}{dx}\\=&\frac{3*-sin(x)}{5}\\=&\frac{-3sin(x)}{5}\\\\ &\color{blue}{The\ third\ derivative\ of\ function:} \\&\frac{d\left( \frac{-3sin(x)}{5}\right)}{dx}\\=&\frac{-3cos(x)}{5}\\=&\frac{-3cos(x)}{5}\\\\ &\color{blue}{The\ 4th\ derivative\ of\ function:} \\&\frac{d\left( \frac{-3cos(x)}{5}\right)}{dx}\\=&\frac{-3*-sin(x)}{5}\\=&\frac{3sin(x)}{5}\\ \end{split}\end{equation} \]
