Differentials Errors and Approximations

Here you will learn what is differentials errors and approximations with examples. Let’s begin – Differentials Errors and Approximations In order to calculate the approximate value of a function, differentials may be used where the differential of a function is equal to its derivative multiplied by the differential of the independent variable, In general dy …

Higher Order Derivatives of Parametric Equations

Here you will learn higher order derivatives of parametric equations with examples. Let’s begin – Higher Order Derivatives of Parametric Equations We know that the differentiation of parametric equations of type x = at and y = 2at is given by formula \(dy\over dx\) = \(dy/dt\over dx/dt\) where t is the parameter Now, by again …

Differentiation of cosec inverse x

Here you will learn differentiation of cosec inverse x or arccosecx x by using chain rule. Let’s begin – Differentiation of cosec inverse x or \(cosec^{-1}x\) : If x \(\in\) R – [-1, 1] . then the differentiation of \(cosec^{-1}x\) with respect to x is \(-1\over | x |\sqrt{x^2 – 1}\). i.e. \(d\over dx\) \(cosec^{-1}x\) …

Differentiation of cot inverse x

Here you will learn differentiation of cot inverse x or arccotx x by using chain rule. Let’s begin – Differentiation of cot inverse x or \(cot^{-1}x\) : The differentiation of \(cot^{-1}x\) with respect to x is \(-1\over {1 + x^2}\). i.e. \(d\over dx\) \(cot^{-1}x\) = \(-1\over {1 + x^2}\). Proof using chain rule : Let …
