hi there, a friend told me this site helped her to understand well so i figured i'd give it a try! i have a few things i'm confused about on my calculus II homework. any tips or pointers would be super
f(x)= (x)/(x-3). find the derivative of the inverse of f(x) at x=2
i found the inverse to be x= y/y-3 but i'm stuck..
An ellipse with equation x^2 + 9y^2= 9 is the base of a solid in which each cross section perpendicular to the x axis is a square. find the volume of the solid.
i drew the graph of the ellipse and now i'm stuck
anyone have any ideas for either of these problems? thank you
