Guida verificata passo dopo passo

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.
