F(x)g(x)dx = F(x)g(x) − ˆ F(x)g′(x)dx where F(x) is an antiderivative of f(x) Remember, all of the techniques that we talk about are supposed to make integrating easier!Answered 5 years ago · Author has 102K answers and 73M answer views The comment is correct, however, sometimes we can integrate by parts This uses the product rule in reverse so to integrate f (x) * g' (x) you get f (x)g (x) integral (g (x)*f' (x)) Ifòf '(x)g(x)dx = f(x)g(x) òf(x)g'(x)dx This is the "integration by parts" formula Whenever you have an integral where the integrand is the product of two functions, you can try to use this formula It is most useful when integrating or differentiating one of the functions in the product will simplify that function
In all the formulas below, f' means \( \frac{d(f(x))}{dx} = f'(x)\) and g' means \(\frac{d(g(x))}{dx}\) = \(g'(x)\) Both f and g are the functions of x and differentiated with respect to x We can also represent dy/dx = D x y Some of the general differentiation formulas are;Yes, we can use integration by parts for any integral in the process of integrating any functionF(x)dx (read integral from a to b of the function f) Answer is a number and does not involve x Notation is convenient Graphical interpretation Z b a f(x)dx is the area of the region in the plane bounded by the graph y = f(x), the xaxis and the vertical lines x = a, x = b 1 2 06–07 Mathematics 1S3 (Timoney) (picture good for case f(x) ≥ 0) Problems need a way to compute

The formula for integration by parts is the following ∫ f(x)g′(x) = f(x)g(x)−∫ f′(x)g(x) ∫ f (x) g ′ (x) = f (x) g (x) − ∫ f ′ (x) g (x)Power Rule (d/dx) (x n )If a function f(x) has integral then f(x) is called an integrable function 2 The process of finding the integral of a function is known as Integration 3 The integration is the reverse process of differentiation Corollary If f(x), g(x) are two integrable functions then ∫(f g)(x)dx± = ∫ ∫f(x)dx g(x)dx± Corollary
