Capitolo 5, Problema 5.5.15a
Use Table 5.6 to evaluate the following indefinite integrals.
(a) ∫ e¹⁰ˣ d𝓍
Guida verificata passo dopo passo1
Step 1: Recognize that the integral involves the exponential function e raised to a linear term (10x). The formula for the integral of e^(kx) is (1/k) * e^(kx) + C, where k is a constant and C is the constant of integration.
Step 2: Identify the constant k in the exponent. In this case, k = 10 because the exponent is 10x.
Step 3: Apply the formula for the integral of e^(kx). Substitute k = 10 into the formula, resulting in (1/10) * e^(10x) + C.
Step 4: Write the result in terms of the indefinite integral. The integral ∫ e^(10x) dx simplifies to (1/10) * e^(10x) + C.
Step 5: Remember to include the constant of integration (C) in your final answer, as this is an indefinite integral.

Indefinite Integrals
Indefinite integrals represent a family of functions whose derivative is the integrand. They are expressed with the integral sign followed by the function and the differential, and they include a constant of integration (C) since the derivative of a constant is zero. Understanding how to evaluate indefinite integrals is crucial for solving problems in calculus, as they provide the antiderivative of a function.

Introduction to Indefinite Integrals
Exponential Functions
Exponential functions are mathematical functions of the form f(x) = a^x, where 'a' is a constant and 'x' is the variable. In calculus, the natural exponential function e^x is particularly important due to its unique property that the derivative of e^x is e^x itself. This property simplifies the process of integration, especially when dealing with integrals involving exponential terms.

Free fall On October 14, 2012, Felix Baumgartner stepped off a balloon capsule at an altitude of almost 39 km above Earth’s surface and began his free fall. His velocity in m/s during the fall is given in the figure. It is claimed that Felix reached the speed of sound 34 seconds into his fall and that he continued to fall at supersonic speed for 30 seconds. (Source: http://www.redbullstratos.com)
(a) Divide the interval [34, 64] into n = 5 subintervals with the gridpoints x₀ = 34 , x₁ = 40 , x₂ = 46 , x₃ = 52 , x₄ = 58 , and x₅ = 64. Use left and right Riemann sums to estimate how far Felix fell while traveling at supersonic speed.

Planetary orbits The planets orbit the Sun in elliptical orbits with the Sun at one focus (see Section 12.4 for more on ellipses). The equation of an ellipse whose dimensions are 2a in the 𝓍-direction and 2b in the y-direction is (𝓍²/a²) + (y² /b²) = 1.
(a) Let d² denote the square of the distance from a planet to the center of the ellipse at (0, 0). Integrate over the interval [ ―a, a] to show that the average value of d² is (a² + 2b²) /3 .
