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