### Hw 1D.9 - radial nodes and angular nodal surfaces differences

In 1D.9 in the 7th edition part c of the question asks about the number of radial nodes and angular nodal surfaces. I recognize only nodal planes from the lecture. For this our purposes for this class what are the significant differences [if any] of radial nodes, angular nodal surfaces, and nodal planes?

Additionally is there a way to calculate either of those or can we only know by memorizing the different orbitals?

We do not need to know radial nodes.
Angular nodal surfaces and nodal planes are the same so the question is asking for how many nodal planes in each.
Calculating them would involve the schrodinger equation which we are not using in class so just memorize them.
