Question

Find the derivative of log x w. r. t. x. (x > 0)​

Answer 1

Given :

f(x)=log x

To find :

derivative of f(x)=log x when x>0

Solution :

Let f(x) = y = log |x|

• When x >0

→ y = log |x| $\:\:$[for only positive values of x]

→ dy/dx = 1/x

So derivative of log |x| wrt to x is 1/x, provided x > 0.

Answer 2

Step-by-step explanation:

Step-by-step explanation:

let y = log x

dy/dx= d(logx)/dy

=1/x
