    Finding Power Series Representation for f(x) and Interval of Convergence

    Homework Statement Find the power series representation for the function f(x)=x/(x^2-3x+2) and determine the interval of convergence. Homework Equations The Attempt at a Solution First I separate into partial fractions 2/(x-2) - 1/(x-1) 2/(x-2) = sum n=0 to infinity (x/2)^n...

    Finding Volume Using Disk and Washer Method: Rotation about the Y-Axis

    Consider the region bounded by the curves y=x^2+1 and y=3-x^2 a) using the disk/washer method, find the volume of the solid obtained by rotating this region about the x axis This was very straight forward v=int(1, -1) pi((3-x^2)^2)-(x^2+1)^2))dx I finished the problem with 32pi/3 which...
