The command \newtheorem{theorem}{Theorem} has two parameters, the first one is the name of the environment that is defined, the second one is the word that will be printed, in boldface font, at the beginning of the environment. For ex-ample, one application lies in polynomial approximation of functions from point-evaluations. OR b) If the real valued function is differentiable at the point ∈ then prove that is continuous at ‘ ’. Using Lagrange’s mean value theoremshow that 1 8 ≤ 51 − 49 < 1 7.

Suppose that the functions \(u\left( x \right)\) and \(v\left( x \right)\) have the derivatives up to \(n\)th order. log x If Bos Communicated by H. FREUDENTHAL & J. R. RAVETZ 2. In calculus, the general Leibniz rule, named after Gottfried Wilhelm Leibniz, generalizes the product rule (which is also known as "Leibniz's rule").
