d lnx
1/x
The expression dlnx represents the derivative of the natural logarithm function of x. To calculate this derivative, we can use the following formula:
d/dx (lnx) = 1/x
Therefore, dlnx = 1/x.
This means that the rate of change of the natural logarithm function of x with respect to x is equal to 1/x. For example, if x = 4, then dlnx = 1/4. This tells us that if we increase x by a small amount, the value of the natural logarithm of x will increase by approximately 1/4.
