There are 1 questions in this calculation: for each question, the 1 derivative of A is calculated.
Note that variables are case sensitive.\[ \begin{equation}\begin{split}[1/1]Find\ the\ first\ derivative\ of\ function\ 0.657189 + 0.315105A - 0.0173158B + 0.610868C - 0.029AB + 0.123368AC - 0.00210526BC - 0.086{A}^{2} + 0.005{B}^{2} - 0.435333{C}^{2}\ with\ respect\ to\ A:\\\end{split}\end{equation} \]
\[ \begin{equation}\begin{split}\\Solution:&\\ &Primitive\ function\ = 0.315105A - 0.029BA + 0.123368CA - 0.00210526BC + 0.610868C - 0.0173158B - 0.086A^{2} + 0.005B^{2} - 0.435333C^{2} + 0.657189\\&\color{blue}{The\ first\ derivative\ function:}\\&\frac{d\left( 0.315105A - 0.029BA + 0.123368CA - 0.00210526BC + 0.610868C - 0.0173158B - 0.086A^{2} + 0.005B^{2} - 0.435333C^{2} + 0.657189\right)}{dA}\\=&0.315105 - 0.029B + 0.123368C + 0 + 0 + 0 - 0.086*2A + 0 + 0 + 0\\=& - 0.029B + 0.123368C - 0.172A + 0.315105\\ \end{split}\end{equation} \]Your problem has not been solved here?
