Differentiate both upper and lower sides wrt x.
lim ( a cosx - sina )/ (2ax - a^2)
Now lim x->a,
Therefore,
Ans = a cosa - sina/(a)^2

tokaians: can you show with the method of limits
NabasishGogoi: lim x->a means lim x-a -> 0 or if h = x-a
then lim h->0 where x = a+h
we use this substitution into the limit
NabasishGogoi: ughhh.. here its not possible to explain wholly
tokaians: so can you edit the answer
NabasishGogoi: yea but idk why the edit answer is not showing.. you've reported I think..
