Essa relação matemática não é aplicada a qualquer tipo de sólido geométrico. Para utilizarmos o Teorema de Euler, o poliedro precisa ser convexo. Assim, podemos chamar também um poliedro convexo de poliedro euleriano, ou seja, que a relação de Euler pode…

Welcome to the awesome 12-part series on the Gaussian integral. In this series of videos, I calculate the Gaussian integral in 12 different ways. Which method is the best? Watch and find out!

In this video, I use Stirling's formula to 'prove' the Gaussian…

In this video, I determine if the function f(x) = [cos(x)]^3 (sin(5x)) is increasing, decreasing or neither at x = pi. Another random old video.

O sistema de posicionamento global (GPS, na sigla em inglês) foi criado pelo Departamento de Defesa dos Estados Unidos, com fins militares, e depois aberto ao uso civil. Atualmente, outros países têm sistemas similares.

What if we have both a negative base and a negative input in a logarithm! People often say we cannot have a negative number inside of a logarithm. Most of the time log(negative) gives us an imaginary number. But since (-2)^3=-8, so what do you think the answer…

This is a tricky SAT/GRE type problem that most people miss. Can you figure it out?
