Answer ::

Question: differentiation of x²-cosx+1/x

$\huge\mathfrak\pink{Solution :-}$

$\displaystyle\boxed{\sf\pink{differentiation \: of \: x^2-cosx+\dfrac{1}{x}}}$

$\displaystyle\sf\red{\dfrac{dy}{dx}=x^2-cosx+\dfrac{1}{x}}$

$\displaystyle\boxed{\blue{\tt\blue{By \: chain\: Rule}}}$

$\displaystyle\boxed{\sf\huge{Formulas::}}$

$\displaystyle\boxed{\small\sf{x^2=2x \:and\: cosx=-sinx \: and \:\dfrac{1}{x}=-\dfrac{1}{x^2}}}$

$\displaystyle\sf\pink{\dfrac{dy}{dx}=2x+sinx-\dfrac{1}{x^2}}$
