Calculus I Integrals of Exponential Functions YouTube
Exponential functions are those of the form \(f(x)=Ce^{x}\) for a constant \(C\), and the linear shifts, inverses, and quotients of such functions. Exponential functions occur frequently in physical sciences, so it can be very helpful to be able to integrate them. Nearly all of these integrals come down to two basic formulas:

Comments. The function $\mathop {\rm Ei}$ is usually called the exponential integral. Instead of by the series representation, for complex values of $ z $ ( $ x $ not positive real) the function $ \mathop {\rm Ei} ( z) $ can be defined by the integal (as for real $ x \neq 0 $); since the integrand is analytic, the integral is path-independent.

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.

The exponential function has a base of e, so we use the integral formula, ∫ e x x d x = e x + C. Since the exponent has − 1 before x, we'll need to use the substitution method to integrate the expression. u = − x d u = − 1 ⋅ d x − d u = d x. Rewrite ∫ e − x x d x in terms of u and d u.

Well, to find the antiderivative (integral) of an exponential function, we will apply the same three steps, except instead of multiply, we will divide! Rewrite. Divide by the natural log of the base. Divide by the derivative of the exponent. ∫ a b x d x = a b x b ( ln a) + C. a: The base of the exponential function.

Finding the derivative of an exponential function is pretty straightforward since its derivative is the exponential function itself, so we might be tempted to assume that finding the integrals of exponential functions is not a big deal. This is not the case at all. Differentiation is a straightforward operation, while integration is not.

The following problems involve the integration of exponential functions. We will assume knowledge of the following well-known differentiation formulas : , and. is any positive constant not equal to 1 and is the natural (base ) logarithm of . These formulas lead immediately to the following indefinite integrals :

Let's rectify that here by defining the function f(x) = ax in terms of the exponential function ex. We then examine logarithms with bases other than e as inverse functions of exponential functions. Definition: Exponential Function. For any a > 0, and for any real number x, define y = ax as follows: y = ax = exlna.

The Derivative of the Exponential. We will use the derivative of the inverse theorem to find the derivative of the exponential. The derivative of the inverse theorem says that if f f and g g are inverses, then. g′(x) = 1 f′(g(x)). g ′ ( x) = 1 f ′ ( g ( x)). Let. f(x) = ln(x) f ( x) = ln ( x) then. f′(x) = 1 x f ′ ( x) = 1 x.
