Is the derivative of an exponential function a logarithmic function?

Exponential functions and their corresponding inverse functions, called logarithmic functions, have the following differentiation formulas: Note that the exponential function f( x) = e x has the special property that its derivative is the function itself, f′( x) = e x = f( x).

What are some examples of how logs and exponential functions are used?

Exponential and logarithmic functions are no exception! Much of the power of logarithms is their usefulness in solving exponential equations. Some examples of this include sound (decibel measures), earthquakes (Richter scale), the brightness of stars, and chemistry (pH balance, a measure of acidity and alkalinity).

How exponential and logarithmic functions are related?

Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. By definition, alogax = x, for every real x > 0.

What is E in derivatives?

This means that the derivative of an exponential function is equal to the original exponential function multiplied by a constant (k) that establishes proportionality. This is exactly what happens with power functions of e: the natural log of e is 1, and consequently, the derivative of ex is ex .

What is the relationship between logarithmic and exponential functions?

Logarithmic functions are the inverses of exponential functions. The inverse of the exponential function y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay.

What is the difference between exponential and logarithmic functions?

The exponential function is given by ƒ(x) = ex, whereas the logarithmic function is given by g(x) = ln x, and former is the inverse of the latter. The domain of the exponential function is a set of real numbers, but the domain of the logarithmic function is a set of positive real numbers.

What is the logarithmic rule for derivatives?

The logarithm rule is a special case of the chain rule. It is useful when finding the derivative of the natural logarithm of a function. The logarithm rule states that this derivative is 1 divided by the function times the derivative of the function.
