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