DTube: Integral of sin^3(x), sin^3(ax) with substitution and trigonometric identity

DTube: Integral of sin^3(x), sin^3(ax) with substitution and trigonometric identity

In this tutorial, we'll work through 2 different approaches to solving the integral of sin3(ax). Now, there maybe more ways of approaching this problem, but these were the most obvious to me. Using a

DTube: Integral of ∫√(a^2 - x^2)dx using a Trigonometric Substitution

What I love about mathematics is some of the very creative and ingenious methods that someone has come up with to find solutions to perplexing problems. The integral of √(a2 - x2) is a great example one

DTube: Modelling the Decay of Nuclear Medicine with dy/dx = -ky

DTube: Modelling the Decay of Nuclear Medicine with dy/dx = -ky

Inasmuch as the differential equation dy/dx = ky models exponential growth, it follows that dy/dx = -ky models exponentially decaying processes. A exponential decay process, which is a slowing reduction

DTube: Modelling Exponential Growth of Bacteria with dy/dx = ky

DTube: Modelling Exponential Growth of Bacteria with dy/dx = ky

With the differential equation dy/dx = ky, we found the general solution to be y(x) = Aekx. We worked this out in my last post. This equation lends itself to the modelling of exponential growth. Now in

DTube: Integral of ∫1/(a^2 + x^2)

DTube: Integral of ∫1/(a^2 + x^2)

The term 1/(a2 + x2) is purely algebraic. However, its integral is trigonometric. When you look this up in a table of integrals, you'll find the integral: ∫1/(a2+x2)dx = (1/a)arctan(x/a) + C How is this

DTube: Reduction Formula for Integral of ∫cos^n(x)dx

DTube: Reduction Formula for Integral of ∫cos^n(x)dx

In this video, we work through the derivation of the reduction formula for the integral of cosn(x) or [cos(x)]n. The first step is to rewrite the integral as: ∫cosn(x)dx = ∫cosn-1(x)cos(x)dx Thus we have
