There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ {x}^{\frac{1}{2}} + {x}^{100} + arctan(x)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = x^{\frac{1}{2}} + x^{100} + arctan(x)\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( x^{\frac{1}{2}} + x^{100} + arctan(x)\right)}{dx}\\=&\frac{\frac{1}{2}}{x^{\frac{1}{2}}} + 100x^{99} + (\frac{(1)}{(1 + (x)^{2})})\\=&\frac{1}{2x^{\frac{1}{2}}} + 100x^{99} + \frac{1}{(x^{2} + 1)}\\ \end{split}\end{equation} \]
