Homework Help: Integration Homework Help

  1. May 3, 2008 #1
    A population of cattle is increasing at a rate of 200 + 10t per year, where t is measured in years. By howmuch does the population increase between the 4th and 6th years. What is the total increase?

    I tried using integration, and have b=6 and a=4, with interval of 2, but it was wrong. Please help me. Thank you!

    [tex]P(t) = \int (200+10t)dt = 200t+ 5t^2[/tex]
    [tex]P(6)-P(4)=?[/tex]

    If you did that and you got it wrong, i really don't know....
