Find the following partial derivative.

$\frac{\text{d}\text{e}\text{l}\text{z}}{\text{d}\text{e}\text{l}\text{y}}{|}_{(4,2\mathrm{.}5)}ifz=e^{x+2y}siny$

Assume the variables are restricted $to$ a domain $on$ which the function $is$

defined.

Round your answer $to$ one decimal place.

$\frac{\text{d}\text{e}\text{l}\text{z}}{\text{d}\text{e}\text{l}\text{y}}{|}_{(4,2\mathrm{.}5)}=$
