There are 1 questions in this calculation: for each question, the 1 derivative of a is calculated.
Note that variables are case sensitive.\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ (\frac{1}{2})(1 - \frac{1}{(a*1.3 + (100 - a)*1.1)}) + (\frac{1}{2})(1 - \frac{1}{(a*1.05 + (100 - a)*1.1)})\ with\ respect\ to\ a:\\\end{split}\end{equation} \]
\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = - \frac{0.5}{(1.3a - 1.1a + 110)} - \frac{0.5}{(1.05a - 1.1a + 110)} + 1\\&\color{blue}{The\ first\ derivative\ function:}\\&\frac{d\left( - \frac{0.5}{(1.3a - 1.1a + 110)} - \frac{0.5}{(1.05a - 1.1a + 110)} + 1\right)}{da}\\=& - 0.5(\frac{-(1.3 - 1.1 + 0)}{(1.3a - 1.1a + 110)^{2}}) - 0.5(\frac{-(1.05 - 1.1 + 0)}{(1.05a - 1.1a + 110)^{2}}) + 0\\=& - \frac{-0.1}{(1.3a - 1.1a + 110)(1.3a - 1.1a + 110)} - \frac{0.025}{(1.05a - 1.1a + 110)(1.05a - 1.1a + 110)}\\ \end{split}\end{equation} \]Your problem has not been solved here?
