Calculus - Using i to evaluate an integral

[@AvoidsPikes-]

I've never liked doing any math, ANY math with the imaginary number i. I liken that number to driving in heavy traffic on a street during rush hour in a rainstorm while that street is being repaired by repairmen. Thanks MySecretMathTutor for another great video. I also forgot that the antiderivative of 1/x is ln(x), so I just got a bit of a refresher.

Great to hear. Guess I should do a few more with the imaginary number so those streets can feel more well traveled. :^D

hi

Instead of that why don’t we substitute x=tan

You could for this one, but I wanted to specifically wanted to show how you might use the number i, without going down the road of contour integrals. :^D
