e to the pi i, a nontraditional take (old version)
The enigmatic equation e^{pi i} = -1 is usually explained using Taylor's formula during a calculus class. This video offers a different perspective, which involves thinking about numbers as actions, and about e^x as something which turns...

Determine the infinite sum of a geometric series
👉 Learn how to find the geometric sum of a series. A series is the sum of the terms of a sequence. A geometric series is the sum of the terms of a geometric sequence. The formula for the sum of n terms of a geometric sequence is given by...

Wave equation: Vibrating String Proof
The 1 dimensional wave equation is solved here using the separation of variables technique (assuming u(x,t) = phi(x) q(t). I simplify the formula further using the boundary conditions: u(0,t) = 0 and u(L,t) = 0 The constants in the final...
