The following problems involve the integration of exponential functions. We will assume knowledge of the following well-known differentiation formulas : , where , and , where a is any positive constant not equal to 1 and is the natural (base e) logarithm of a. These formulas lead immediately to the following indefinite integrals :
To find the integral of an exponential function b x, you reverse the derivative process. The integral is given by the formula: b x ln (b) + c. where b is the base of the exponential function, ln(b) is the natural logarithm of b, and c is the constant of integration. This formula is applicable when b is greater than zero and not equal to one.
General Logarithmic and Exponential Functions. We close this section by looking at exponential functions and logarithms with bases other than \(e\). Exponential functions are functions of the form \(f(x)=a^x\). Note that unless \(a=e\), we still do not have a mathematically rigorous definition of these functions for irrational exponents.

Contributors; Exponential and logarithmic functions are used to model population growth, cell growth, and financial growth, as well as depreciation, radioactive decay, and resource consumption, to name only a few applications.
Some Useful Integrals of Exponential Functions Michael Fowler . We’ve shown that differentiating the exponential function just multiplies it by the constant in the exponent, that is to say, ax ax. d eae dx = Integrating the exponential function, of course, has the opposite effect: it divides by the constant in the exponent: 1 edx e ax ax , a ...
If the parameter n equals 0,-1-2,…, the exponential integral EnHzL can be expressed through an exponential function multiplied by a simple rational function. If the parameter n equals 1,2,3,…, the exponential integral EnHzL can be expressed through the exponential integral Ei HzL, and the exponential and logarithmic functions: E0HzL− ª-z z
To find the integral of an exponential function, use the rule: b x / ln (b) + C, where b > 0 and b ≠ 1. For the special case of e x, the integral simplifies to e x + C.Apply these rules to evaluate integrals involving constants and sums, ensuring to separate terms and utilize the constant multiple rule effectively.
As mentioned at the beginning of this section, exponential functions are used in many real-life applications. The number e is often associated with compounded or accelerating growth, as we have seen in earlier sections about the derivative. Although the derivative represents a rate of change or a growth rate, the integral represents the total change or the total growth.
Practice integrating various indefinite and definite integrals involving exponential functions to build your skills. Use your knowledge of exponent and logarithmic properties to simplify integrands and solutions effectively.

IN3.3 Integration of Exponential Functions This module deals with differentiation of exponential functions such as: exp(2x +3)dx e3xdx 2 1 ex 1dx. Indefinite Integral of an Exponential Function If f (x) = e xthen f0(x) = e . Therefore an antiderivative (or indefi-nite integral) of ex is ex. That is exdx = ex +c, where c is a constant.

In this section, we will take a look at exponential functions, which model this kind of rapid growth. Identifying Exponential Functions. When exploring linear growth, we observed a constant rate of change - a constant number by which the output increased for each unit increase in input.
