[DTube] Integral of ∫dx/sqrt(1-x^2)

I'm in the process of uploading all of my Youtube videos to DTube, where they can be recorded on the Steem blockchain.

In this video, we work through the steps to find the indefinite integral or anti-derivative of:

∫dx/sqrt(1-x^2)

with the term 1 - x^2, it is indicative of a trigonometric substitution, so we try:

x = sin(theta) with dx = cos(theta)

1. Integral of ∫dx/sqrt(1-x^2)
2. Integral of ∫√(a^2 - x^2)dx
