I have a question strangely worded and I don't have the solution so I wanted to make sure I was doing it right
I know I am supposed to use the inverse chain rule to solve this.
I have subbed in sqrt(x)-1 into the x already inside the integral, then subbed the x into that new function to get
integral ( 1/4 * d/dx( sqrt(sec(x) -1))
then solved for the derivative to get
integral ( 1/4 * ( 1/2*(sec(x)-1)^-(1/2) * sec(x)tan(x) ) )
so then used the inverse chain rule to get
1/4 * (sec(x)-1)^(1/2) + c
would this be correct?
