Homework Statement
I want to know the expression for the round metric of an n-sphere of radius r
Homework Equations
I have obtained this for a 3-sphere
dS^{2}=dr^{2}+r^{2}(d\theta_{1}^{2}+sin^{2}\theta_{1}d\theta_{2}^{2}
+sin^{2}\theta_{1}sin^{2}\theta_{2}d\theta_{3}^{2})
The Attempt at a Solution
what will be the general expression for an n -sphere
