So, I taught myself differential calculus yesterday, but I'm a bit puzzled when it comes to PDEs. It is essentially a differential equation treating everything other than a single variable as a constant?

Pic related, it's what I'm working on

Not when derivatives in respect to several variables are involved.

No, a differential equation is finding an equation for f (or in this case phi) that satisfies the equation. When taking a partial derivative one treats the variables one isn't differentiating with respect to as constants.

There are a lot of things you should study before you try to solve Schrodingers equation
