These are just some notes and explanations of different topics in Math/Physics that I have found interesting and have some relationship to electrical principals and electrical engineering.

(1) Maxwell's Equations (converting from integral to differential form)

(2) Electromagnetic wave equations (for electric and magnetic fields)

(3) Electromagnetic waves (part II). Relating E, B to direction of wave propagation

(4) Electromagnetic waves (part III). Proving E and B are mutually orthogonal

(5) Time Independent Schrodinger Equation

(6) Various Topics/solution methods regarding Differential Equations
