Hi, I have to do alot of integration questions for my astoronomy class but I'm not really sure how to! for example how do u integrate from a number lets say a = 0, to a = 1/(1+z).... and dt = \frac{da}{H_0 \left(\frac{\Omega_{m,0}}{a} + a^2 \Omega_{\Lambda,0}\right)^{\frac{1}{2}}}(adsbygoogle = window.adsbygoogle || []).push({});

I've done a different kind of simple integration but i have no idea how this works,. thanks!

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
