The following is a list of integrals (antiderivative functions) of logarithmic functions. For a complete list of integral functions, see list of integrals. Note: x > 0 is assumed throughout this article, and the constant of integration is omitted for simplicity.

Integral formulas for other logarithmic functions, such as \(f(x)=\ln x\) and \(f(x)=\log_a x\), are also included in the rule. Rule: Integration Formulas Involving Logarithmic Functions. The following formulas can be used to evaluate integrals involving logarithmic functions.

Math formulas: Integrals of logarithmic functions. 0 formulas included in custom cheat sheet: List of integrals involving logarithmic functions $$ \int \ln(cx)dx = x\ln(cx) - x $$ $$ \int \ln(ax+b)dx = x\ln(ax+b) - x + \frac{b}{a}\ln(ax + b) $$ $$ \int (\ln x)^2dx = x(\ln x)^2 - 2x\ln x + 2x $$ ...

We can factorize a bit and get the desired formula \[\int \ln(x)\ dx = x\big(\ln(x) - 1\big) + C.\ _\square\] This shows that an unlikely application of an integration technique can actually be the right way forward! Now that we know how to integrate this, let's apply the properties of logarithms to see how to work with similar problems.

The integration of log x with base e is equal to xlogx - x + C, where C is the constant integration. The logarithmic function is the inverse of the exponential function.Generally, we write the logarithmic function as log a x, where a is the base and x is the index. The integral of ln x can be calculated using the integration by parts formula given by ∫udv = uv - ∫vdu.

Integral formulas for other logarithmic functions, such as [latex]f(x)=\text{ln}x[/latex] and [latex]f(x)={\text{log}}_{a}x,[/latex] are also included in the rule. Integration Formulas Involving Logarithmic Functions. The following formulas can be used to evaluate integrals involving logarithmic functions.

Write the definition of the natural logarithm as an integral. Recognize the derivative of the natural logarithm. Integrate functions involving the natural logarithmic function. Define the number \(e\) through an integral. ... which leads immediately to the integration formula \[ ∫e^x \,dx=e^x+C. \nonumber \] We apply these formulas in the ...

where is the Euler-Mascheroni constant (Nielsen 1965, pp. 3 and 11; Berndt 1994; Finch 2003; Havil 2003, p. 106). Another formula due to Ramanujan which converges more rapidly is

The following formula can be used to evaluate integrals in which the power is \(-1\) and the power rule does not work. \[ ∫\frac{1}{x}\,dx =\ln |x|+C\] In fact, we can generalize this formula to deal with many rational integrands in which the derivative of the denominator (or its variable part) is present in the numerator.

Thanks to this formula, integral of all power functions becomes pretty straightforward. Evaluate the following integral: $$\int(x^4-2x^2+x^{\text{-}1}-x^{\text{-}3})\mathrm{d}x$$ We begin by noting that the integral can be split into 4 integrals. ... Integration of Logarithmic Functions Formula.
