    Finding power series representation and sum from a given function

    Okay so my math in getting https://www.physicsforums.com/latex_images/26/2602939-0.png was right? and because it's a geometric series I can use a/1-r to find the sum right?

    Finding power series representation and sum from a given function

    Okay with the limits of integration substituted I got http://www2.wolframalpha.com/Calculate/MSP/MSP344199e931ddgafc99d0000507h04h0277efcda?MSPStoreType=image/gif&s=9&w=34&h=37 and then i find the first 3 nozero terms from that right?

    Finding power series representation and sum from a given function

    Ok so for the integral I got http://www4a.wolframalpha.com/Calculate/MSP/MSP758199e8ha121cf0a4c00004ggc11fi1gf83a0h?MSPStoreType=image/gif&s=29&w=34&h=40 Is that right? and from that is the sum: infinity?

    Finding power series representation and sum from a given function

    Okay so how exactly would I integrate this? Seeing as there are two variables.

    Finding power series representation and sum from a given function

    Agh! Ok I'm confused. If I'm just taking the integral of the general form, do I still need those limits? Or am I doing a Fundamental Theorem thing?

    Finding power series representation and sum from a given function

    Ok, I understand that, but what exactly are the limits of integration (0,1) there for?

    Finding power series representation and sum from a given function

    Okay so I can just take the integral of the general term and find the sum of the first 3 nonzero terms?

    Finding Derivative of (1-x^2)^-1/4: Solving for 0

    How would I find the derivative of (1-x^2)^-1/4? y = 1 + x - x^2 - x^4 I found the derivative to be 1 - 2x - 4x^3, but I need help solving it for 0. Thanks for your time.

    Minimize cost of pipe from offshore rig to refinery

    Homework Statement A drilling rig 12 miles off shore is to be connected by a pipe to a refinery onshore, 20 miles down the coast from the rig. If underwater pipe costs $40,000 per mile and land based pipe costs $30,000 per mile what value of x and y would give the least expensive connection...
