There are 1 questions in this calculation: for each question, the 1 derivative of a is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 2{a}^{4} - \frac{5}{2}{a}^{2} - 3a + \frac{117}{16}\ with\ respect\ to\ a：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 2a^{4} - \frac{5}{2}a^{2} - 3a + \frac{117}{16}\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( 2a^{4} - \frac{5}{2}a^{2} - 3a + \frac{117}{16}\right)}{da}\\=&2*4a^{3} - \frac{5}{2}*2a - 3 + 0\\=&8a^{3} - 5a - 3\\ \end{split}\end{equation} \]
