Exponential Indefinite integration Problems and Solutions

In calculus, the exponential functions are involved in forming the mathematical functions in some cases. For calculating the integrals of the functions in which exponential functions are involved, the integral rules of exponential functions are used. The following problems are the list of integration problems with solutions to learn how to find the integration of the functions in which exponential functions are involved.
