There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ \frac{2tan(\frac{0.93x}{2})}{tan(\frac{0.93}{2})}\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( \frac{2tan(0.465x)}{tan(0.465)}\right)}{dx}\\=&\frac{2*-sec^{2}(0.465)(0)tan(0.465x)}{tan^{2}(0.465)} + \frac{2sec^{2}(0.465x)(0.465)}{tan(0.465)}\\=&\frac{0.93sec^{2}(0.465x)}{tan(0.465)}\\ \end{split}\end{equation} \]
