I'm trying to solve this integral but I'm not sure if I'm on the right track. My question is: can this integral be solved by partial fractions decomposition? I solved the problem that way but I'm not sure if it is the right answer. thanks! ∫1-x+2x^2-x^3 ÷ x(x^2+1)^2

thank you very much...i'm going to see if I can solve it using this :)

I'm solving a calculus problem which requires me to equate both equations, but I can't isolate X: √x = e^-3x What I've got so far is: ln√x = ln e^-3x ln√x = -3x 1/2 ln x = -3x ln x = -6x ... but from here I can't continue, please help:frown:

"Work" (Calculus II) This is a problem from the chapter called "Work": A water tank in the form of an inverted right-circular cone is 29 ft across the top and 15 ft deep. If the surface of the water is 5 ft. below the top tank, find the work done in pumping the water to the top of the tank...
