# How do you differentiate #y=sin^(2)x + cos^(2)x#?

or we can do it this way.

God bless....I hope the explanation is useful.

To differentiate ( y = \sin^2(x) + \cos^2(x) ), you can use the fact that ( \sin^2(x) + \cos^2(x) = 1 ) for all ( x ). Therefore, the derivative of ( y ) with respect to ( x ) is ( 0 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
