There are 1 questions in this calculation: for each question, the 1 derivative of x is calculated.
    Note that variables are case sensitive.
\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ a(a + 1)(a + \frac{7}{2})(a + 3 + j*2)(a + 3 - j*2)\ with\ respect\ to\ x：\\\end{split}\end{equation} \]\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - 4a^{3}j^{2} - 18a^{2}j^{2} - 14aj^{2} + \frac{21}{2}a^{4} + \frac{79}{2}a^{3} + \frac{123}{2}a^{2} + a^{5} + \frac{63}{2}a\\&\color{blue}{The\ first\ derivative\ function：}\\&\frac{d\left( - 4a^{3}j^{2} - 18a^{2}j^{2} - 14aj^{2} + \frac{21}{2}a^{4} + \frac{79}{2}a^{3} + \frac{123}{2}a^{2} + a^{5} + \frac{63}{2}a\right)}{dx}\\=& - 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0\\=&0\\ \end{split}\end{equation} \]
