DISCLAIMER due to an arithmetic error, the answer is off by a factor of 7, but the trigonometric substitution operation was still preformed correctly.
Evaluate the integral:
(sqrt(81x^2 -49)/(x^3) dx

I think for sake of completion you should still substitute back in what theta is in terms of x.

i still don’t understand how you thought of this in the first place, like how does it makes sense?

This is a substitution method used by mathematicians that do calculus that I had learned earlier, if you have any further questions I can clear up any confusion on a particular subject!

​@@kinetictutoring-ku4wk Thanks for the solution, just 1 issue, while factoring out 9 cube and nine you only left a 9 instead of 9 square

is it not 9^2 /7 since its 9^3/9^1 = 9^2

I guess my question is im confused when you go from taking the constant out of the integral

@@pabloooooooooooo6621 just for the sake of simplicity it looks cleaner in my opinion

yes when he crossed out terms and brought the constant outside the integral he forgot to include 9^2
