Homework Statement
Function defined as:
y = The integral from 0 to x2 of 1 / (1 - Sqrt(t) + t)
There exists a point where the slope of the tangeant is = -2. Find the x coordinate at this point.
Homework Equations
Fundemental Theorem of Calculus
The Attempt at a Solution
If I use FTC and replace t with x2. Then I get two equations because sqrt(x2) is +/- x. I use those to create two separate equations.
y = 2x and y = 2x/1+2x
These should be 2 equations for the tangeant line but I am unsure what to do next.
This was on my exam yesterday and I tried some things, none of which seemed right. I know I lost mark just would like to know how many. :)
