There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 3{x}^{2} - {5}^{cos(x)} - 1\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 3x^{2} - {5}^{cos(x)} - 1\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 3x^{2} - {5}^{cos(x)} - 1\right)}{dx}\\=&3*2x - ({5}^{cos(x)}((-sin(x))ln(5) + \frac{(cos(x))(0)}{(5)})) + 0\\=&6x + {5}^{cos(x)}ln(5)sin(x)\\ \end{split}\end{equation} \]
