Answer.

Leibnitz’s theorem

Statement: Let u(x) and v(x) be n^th order differentiable functions

Q2. Define Tautology and contradiction. Show that

Answer.

Lagrange’s Theorem

Let f: [a,b] ->R be a continuous function such that f: (a,b)->R is differentiable. Then, there exists c ε (a,b) such that [f(b)-f(a)]/(b-a)  =f’(c).

Answer.

Solution: (i) We have  (𝑥²+𝑦²)x−𝑎𝑦²=0

Or  x³+(x-a)y²=0

Asymptote parallel to x – axis are obtained by equating to zero the coefficient of the highest power of x. Since
