So far, we've learned about a couple of basic methods of integration: for instance, we know that integrals add: ∫[f(x)−g(x)] dx=∫f(x) dx−∫g(x) dx.\int [f(x)-g(x)]\, dx=\int f(x)…

Integration by parts is a powerful tool that results from reversing the Product Rule. Of course, while ∫f′(x)g(x)+f(x)g′(x)dx=f(x)g(x)\int{f'(x)g(x) + f(x)g'(x)dx} = f(x)g(x)∫f′…

How do we do an integration that is the product of 2 functions? For example... how do we integrate xsin⁡3xx \sin3xxsin3x dx? If xxx or sin⁡3x\sin3xsin3x were by themselves we co…

First we will talk about how we derive the formula for integration by parts from the product rule of derivation. The product rule states that d/dx[f(x)g(x)]=f′(x)g(x)+f(x)g′(x)d…

A very common mistake people make with integration is seen below: if one were to plug in f(x)=xf(x)=xf(x)=x and g(x)=1g(x)=1g(x)=1 you will instantly realize that the idea above…

In Calculus 1 we learned about the product rule for differentiation ddxuv=duv+udv\frac{d}{dx} uv = duv+udvdxduv=duv+udv Integration by parts is the method for reversing the pro…
