Calculus - ADVANCED Integration - ln(x+sqrt(x^2-1)) - (REQUEST)

find the area of the region such that 0 less than x less than sqrt(2) and 0 less than y less than ln(x+sqrt(x^2-1))

8:33 Wouldn't sqr(x^2-1) be the sinus and not the tangent?

when you replaced dx with dtheta you forgot to change the limits to be based on theta instead of x

should be from arcsec (1) to arcsec (sqrt(2))
