Today we take a look at a funky exercise I call the diamond fraction. We are going to generalize it using double and regular factorials, it's gotta be a ton of fun :) Enjoy!

Today we want to proof the very important analysis result called arithmetic - geometric - harmonic mean inequalities. At first we prove a Lemma, which is going to make the main proof of the theorem really trivial :) Enjoy! =D

Today we are going to calculate the solution to the nonlinear pendulum differential equation, its period time for certain initial displacements, gravitational acceleration and string length. We implement the complete elliptic integral of the first kind into python and approximate the period time to a certain degree. Enjoy :) Video sponsored by Wondershare btw! =)
------------------------------------
The Code:
import math
def elliptic(n,k):
k = math.sin(k *math.pi / 360)
s = 1
for i in range(0, n+1):
p = 1
for j in range(1, 2*i+1+1 , 2):
p *= j / (j+1)
s += (p * k**(i+1))**2
return float(math.pi/2 * s)
l = int(input("String length l? "))
g = float(input("Gravitational acceleration g? "))
phi = float(input("Initial displacement phi_0? "))
n = int(input("Degree of approximation n? "))
print('')
print("Period time T =", 4*math.sqrt(l/g)*elliptic(n, phi))

Today we derive a wonderful expression for the integral from 0 to infinity of sin(xt)/te^(-zt). We will make use of the Leibniz Rule for integration / Feynman Integration to get a final expression in terms of the arctan. Enjoy this beauty! =D

2:47 Confused about this segment? See description!
Context: Still had this video lying around ready to be posted. But I dropped posting it due to the sponsor. It was some Chinese learning app that I already didn't find too appealing to be sponsored on the channel tbh. To add a little twist to the whole thing I at least called the anime char from the app oppai-chan. But one day the sponsors googled what it means and they found out I called her titty-chan xD They weren't fine with it so I simply dropped the sponsorship. you're whalecum lol
Today I challenge you to solve this seemingly simple maths problem: Construct a square using only straight edge and compass. Can you figure it out? Enjoy! =)

Today we are going to introduce the so-called Product Integral and are going to apply its naturally arising definition to the integral x^(dx)-1! Introducing the limit definition of the natural logarithm ln(x) and talking about riemann sums is going to help us solve this bad boi! Enjoy =)
