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