Homework Help: How do I integrate these 3 functions?

  1. Oct 4, 2004 #1
    :confused: How do I integrate these 3 functions?

    (1) [tex]\alpha(t-t_{0})=\int_{R_{0}}^{R(\Theta)}\frac{du}{u\sqrt{a^ 2-u^2}} [/tex]

    (2) [tex]\beta(t-t_{0})=\int_{R_{0}}^{R(\Theta)}\frac{du}{u\sqrt{u^ 2+b}} [/tex]

    (3) [tex]\beta(t-t_{0})=\int_{R_{0}}^{R(\Theta)}\frac{du}{u\sqrt{u^ 2-b}} [/tex]

    A million thanks in advance. :smile:

    The first one can be solved by letting u=asint
    The second and the third is with u=sqrt(b).sint/cost
    The rest is left for you, honey! :wink:
