The Schrodinger Equation in Polar Coordinates

"The right-hand-side depends only on $r$ and the left-hand-side depends only on $\theta$"

Should read: "The left-hand-side depends only on $r$ and the right-hand-side depends only on $\theta$"

The Angular Schrödinger equation in Polar Coordinates

To follow up, in the following section, the notebook reads "To find the solution, we first solve the set the left-hand-side equal to a constant", it should read "right-hand-side" instead of "left-hand-side"
