From where did n came n times mu^2 ???
Doubt regarding n in the derivation
hey @gauthampkrishnan ,
In the given derivation mu^2 is a constant , so if we add a constant n times then we would a resultant as:
n*(mu^2) , hence this how we get n in n times mu^2. ( mu is the mean of values )
I hope this would have resolved your issue.
Happy Learning.
