Now in my textbook it shows the following partial derivative solution:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\frac{d}{dx}[/tex](3y[tex]^{4}[/tex] + e[tex]^{x}[/tex] sin y) = e[tex]^{x}[/tex] sin y

I thought since it's meant to be the partial derivative in terms of x that the y variable would be untouched.

What's happening?
