Trigonometric Substitution for Integrals: Example 3 (DTube)

in dtube •  19 days ago  (edited)


In this video I go over another example on trig substitution for integrals and solve the integral of 1/(x^2*sqrt(x^2+4)). In this example I use the trig substitution x = 2tanθ.

I don't always solve integrals using trig substitution but when I do I usually make sure to convert back to the x variable ;)
