Question

Differentiate with respect to x
a) 2 + sin x​

Answer 1

cos x

Explanation:

d( 2 + sin x )/DX

= d( 2 )/dx + d( sin x )/dx

= 0 + cos x

= cos x

Note : -

1. Differentiation of any number with respect to any variable ( here x ) is 0.
2. Differentiation of sin x is cos x.
3. d/dx is the notation to denote Differentiate with respect to x.
