Find a potential function \( \varphi \) to evaluate \( \int_{C} F . d \mathbf{r} \) (Theorem \( 9.9 .1 \) of the textbook) for \( C \) from the first point to the second. ( \( 10 \mathrm{pts}) \) \[ \mathbf{F}(x, y, z)=e^{x} \cos (y) \mathbf{i}-e^{x} \sin (y) \mathbf{j} \text { from }(0,0) \text { to }(2, \pi / 4) \]
