Question
Find an equation of the tangent plane to the surface at the given point.$$z=e^{x}(\sin y+1), \quad\left(0, \frac{\pi}{2}, 2\right)$$
Step 1
The partial derivative with respect to $x$ is given by: \[f_x = \frac{\partial z}{\partial x} = e^{x}(\sin y+1)\] The partial derivative with respect to $y$ is given by: \[f_y = \frac{\partial z}{\partial y} = e^{x}\cos y\] Show more…
