There are 1 questions in this calculation: for each question, the 1 derivative of A is calculated.
Note that variables are case sensitive.\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 0.7 + 0.3A - 0.02B + 0.6C - 0.03AB + 0.12AC - 0.002BC - 0.1{A}^{2} + 0.005{B}^{2} - 0.04{C}^{2}\ with\ respect\ to\ A:\\\end{split}\end{equation} \]
\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.3A - 0.03BA + 0.12CA - 0.002BC + 0.6C - 0.02B - 0.1A^{2} + 0.005B^{2} - 0.04C^{2} + 0.7\\&\color{blue}{The\ first\ derivative\ function:}\\&\frac{d\left( 0.3A - 0.03BA + 0.12CA - 0.002BC + 0.6C - 0.02B - 0.1A^{2} + 0.005B^{2} - 0.04C^{2} + 0.7\right)}{dA}\\=&0.3 - 0.03B + 0.12C + 0 + 0 + 0 - 0.1*2A + 0 + 0 + 0\\=& - 0.03B + 0.12C - 0.2A + 0.3\\ \end{split}\end{equation} \]Your problem has not been solved here?
