I'm quite stucked at integrating functions

  1. May 30, 2012 #1
    1. The problem statement, all variables and given/known data
    Hello, I'm new here and it seems that this place would be the right place to post, well, I'm just starting up with Integral Calculus, and I think I'm stucked up with integrating fractions like this one.
    Integral of 3/t^4 dt from 1 to 2

    2. Relevant equations

    yeah I mention ot above, oh, one more example,
    integral of x^2+1 all over sqt of x dx from 1 to 2

    3. The attempt at a solution
    I'm quite stucked up! :(

    Thank you!

    Hello khael14. Welcome to PF !

    Here at Physics Forums, we like to see what you have tried, before we give you help. :smile:

    What have you tried? --- or --- What do you understand about integration relative to differentiation?

    Where are you stuck?

    Do you know the integral

    [tex]\int x^n dx[/tex]

    where n is an integer not equal to -1??
