🆕 Dr. Peyam's Show: Integral of square root of x^2 + 1
YouTube
Integral sqrt(x^2+1)
In this video, the second one of the trig integration trilogy (the first one being the square root of 1-x^2), I find an antiderivative of the square root of x^2 + 1 using a trig substitution. Along the way, I also find an antiderivative of sec^3(x). Enjoy!
