Question

differential coefficient of cos x° with respect to x is _______​

Answer 1

Step-by-step explanation:

We have,

$y = \cos(x \degree)$

$\implies \: y = \cos( \frac{\pi x}{180} )$

$\implies \frac{dy}{dx} = - \sin( \frac{\pi x}{180} ) . \frac{\pi}{180}$

$\implies \frac{dy}{dx} = - \frac{\pi}{180} \sin(x \degree )$
