    Chain Rule problem (need to simplify it I think, but don't know how to proceed)

    Find derivative of f(x)=2x^7(2x^5+1)^.5 So I get: d/dx= 14x^6(2x^5+1)^.5 + 2x^7(2x^5+1)^-.5 (5x^4) .....and that's all I got. plz help.

    please help to proceed

    let I subset from R be an interval of the form [a, b],[a, b),(a, b] or (a, b) for a, b belong to R satisfying a less then or equals b . Define the length of such an interval I to be b-a . A box in R^d is a Cartesian product B=I_1 x ...x I_d if intervals in R . Define the length of such a box B...

    Polynomial Problem and not a clue how to proceed

    I'm on my last problem for my lesson and I'm a little stumped and need a push in the right direction. Problem: "One factor of 4x^3+15x^2-31x-30 is x-2. Find the other factors." I don't want the answer but if someone could explain to me how they even got x-2 as a factor I should be able to...

    Strange antiderivative problem... how to proceed?

    If the function f is defined by sqrt(x^3+2) and if g is an antiderivative of f such that g(3)=5, then what is g? I'm not sure what method to integrate f. Trig sub? Integ by parts? Any help is appreciated.
