What is the integral of∫xlnxdx? Question: What is the integral of∫xlnxdx? Integration by Parts: Iff(x)is a logarithmic function andg(x)is an algebraic function then integration off(x)⋅g(x)is given by ∫f(x)⋅g(x)dx=f(x)∫g(x)dx−∫[∫g(x)dxd(f(x))dx]dx....
To find the value of given integral, we use the product rule of integration here. That is, if the integrand can be written as a product of two functionsf(x)andg′(x), then the integral can be solved as follows: ∫f(x)g′(x)dx=f(x)g(x)−∫f′(x)g(x)dx ...
Integral of natural logarithm The integral of the natural logarithm function is given by: When f(x) = ln(x) The integral of f(x) is: ∫f(x)dx= ∫ln(x)dx=x ∙(ln(x) - 1) +C Ln of 0 The natural logarithm of zero is undefined: ...
