Heya all
I need to integrate the following function for an exercise in general relativity. The question is: Find the proper distance between two spheres R[sub]1[\sub]and R[sub]2[\sub] given the metric . So my function is
.
First I thought that I could substitute . However, this doesn't work out. Then I thought that in general what you would actually use here would be let then your becomes , hoping to get under the line as well. In fact your left with How would you compute it?
Thanks in advance
