Well I just finished my Chem Final for the semester, and regardless of my performance, the past week I've been studying everything from the foundational concepts to broader theories.
At the end of it all, I feel that I have a much better grasp on chemistry, which does not seem as hard as...
How do you know to use Lhopitals rule?
Whats the rule when you're dealing with infinity-I already know the 0/0, just not infinity.
Deriving top and bottom expression should yield
xe^(x^2)+F(x)
x^2(e^(x^2))(2x) <-- (chain rule, right?)
Yeah...I'm still stumped.
I don't know how to do this one, let alone apply the fundamental theorem.
How should one come about the solution to these problems?

I don't know how to integrate e^(t^2) like that. I am thinking that it become e^(t^2+1) with some constant in front of the whole expression.
And then with A) I just don't know how to begin.
A kick in the right direction would help...
I think I got it. Knowing constant velocity did help.
Given the top of the loop circumstances, the only forces acting upon the car are N and W, together they equal the centripetal force.
Keeping the same velocity at the bottom, the N and W act against each other, but the centripetal force...
Accelerating as in change of direction?
I would think that the bottom of the loop is the maximum speed of the car, past that half the car begins to decelerate, no?

A free body diagram of the car at the bottom would just incorporate a downwards W force and an upwards N force together equalling 0...
