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