Question

differentiate 2x- 1/x + tanx
for class 11​

Answer 1

Answer:

$Y =2x - \frac{1}{x} + tanx$

Differnatatiating with respect to X

$\frac{dy}{dx } = \frac{d(2x)}{dx} - \frac{d( \frac{1}{x} )}{dx} + \frac{d(tanx)}{dx}$

$\frac{dy}{dx} = 2 - ( \frac { - 1}{ {x}^{2} } ) + sec {}^{2} x$

$\frac{dy}{dx} = 2 + \frac{1}{ {x}^{2} } + sec {}^{2} x$
