Answer 1

Hello chetana

There will be 4 derivatives of second order as if we have k variables then the formula will be ( x + k -1), (k-1).this is the formula for second order derivatives.

For an explained answer please go to math stack exchange website.they have a very good illustrations, also this will depend upon the functions itself.

I hope it helps
