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: The math behind your Camping Torch with dy/dx = -ky

DTube: The math behind your Camping Torch with dy/dx = -ky

We can apply the principle of exponential decay to find equations that model the charge remaining in a capacitor as it is discharged through a resistor. The circuit diagram is shown below... When the switch

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

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
