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 ...
Integrals of exponential functions. Since the derivative of ex is e x;e is an antiderivative of ex:Thus Z exdx= ex+ c Recall that the exponential function with base ax can be represented with the base eas elnax = e xlna:With substitution u= xlnaand using the above formula for the integral of e;we have that Z axdx= Z
In this section we derive integration formulas from formulas for derivatives of logarithms, exponential functions, hyperbolic functions, and trigonometric functions.

The integral is the area between the curve 1 y x and the lines x = 1 and x = 3. From the graph, you can see that this area is not defined, as it includes the value x = 0 for which the function 1 y x is not defined!

View PDF HTML (experimental) Abstract: This paper studies rings of integral piecewise-exponential functions on rational fans. Motivated by lattice-point counting in polytopes, we introduce a special class of unimodular fans called Ehrhart fans, whose rings of integral piecewise-exponential functions admit a canonical linear functional that behaves like a lattice-point count.
