## Difference Between Partial and Total Derivative

Here you will learn by example what the difference is between the partial derivative and the total derivative.

Here you will learn by example what the difference is between the partial derivative and the total derivative.

In this video you will learn what Fourier series / coefficients are and how to specify / calculate them for a function.

In this video you will learn what the Dirac delta function is. We also derive its properties and make examples.

In this physics video you will learn what Hermitian operators and matrices are and what important properties they have.

Learn how to solve 2nd order (in)homogeneous linear differential equations using the exponential ansatz. The DEQ of the harmonic oscillator is solved.

Learn how to solve partial differential equations (PDE) with separation of variables (product ansatz). Here we make an example with the one-dimensional wave equation.

Here you will learn how to solve 1st order homogeneous linear differential equations using the "separation of variables" solving method.

Learn how to solve 1st order inhomogeneous linear differential equations using the "variation of constants" (variation of parameters) method.

Learn the Divergence Theorem in only 8 minutes, namely how it links a volume integral with a surface integral.

In this Lecture you will learn to classify and to solve arbitrary differential equations (ODE / PDE) in 42 minutes.
