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