But what is a Fourier series? From heat flow to drawing with circles | DE4
Fourier series turn a messy, real-world initial condition—like a discontinuous step in temperature—into a controlled sum of simple, rotating...
But what is the Fourier Transform? A visual introduction.
Fourier analysis is built around one practical question: given a signal that’s messy in time—like the air-pressure trace from a sound—how can it be...
What is Euler's formula actually saying? | Ep. 4 Lockdown live math
Euler’s formula stops being a mysterious “imaginary exponent” once the exponential function is treated as a specific power series (exp), not as...
The Physics of Euler's Formula | Laplace Transform Prelude
The core insight is that exponentials of the form e^(st) aren’t just convenient guesses for differential equations—they encode the relationship...
Fourier Transform 2 | Trigonometric Polynomials [dark version]
Fourier series set up approximations of periodic functions by building them from sine and cosine waves, and the key move is to standardize everything...
