So xe − x2 and e − x2 are elementary functions. Here are some examples illustrating how to ask for an integral using plain English. See explanation. In order to integrate ex2dx we need an x so that we can use substitution. So we want to integrate 1 2x2(1 − cos 2x) 1 2 x 2 ( 1 − cos 2 x), that is, x2 2 + x2 2 cos 2x x 2 2 + x 2 2 cos 2 x, which looks

Math can be an intimidating subject.
We use a trick to get a reduction formula: $$ \frac{1}{(x^2+a^2)^{3/2}} = \frac{1}{a^2} \frac{x^2+a^2-x^2}{(x^2+a^2)^{3/2}} = \frac{1}{a^2} \frac{1}{\sqrt{x^2+a^2}} - \frac{1}{a^2}\frac{x^2}{(x^2+a^2)^{3/2}}. en.
This is called a double integral.
Common Integrals. Let u = x and dv = ex2 xdx. Using partial fraction expansion 1 (1 + x2)(a2 + x2) = 1 (a2 − 1)[ 1 (1 + x2) − 1 (a2 + x2)] you can reduce it onto more elementary integrals which you can compute easily. The first has an elementary indefinite integral. The second doesn't. en. the first one gives cos^2 = 1-sin^2, and so we have identities that can be used to simplify 1-x^2 as well as 1+x^2, by putting x = sin (t) or x = tan (t). The computation will look and feel very different, but it still gives the same result. ∫atanθ√tan2θ = ∫atan2θdθ. Math Input.

So, we get. dx = asecθtanθdθ. I'm 7 years removed from taking calculus so I'm admittedly forgetful of the fine details on this. I integrated over the path that goes from -R to R along the real axis and then along a the semi-circle that goes back to -R in the upper half plane. Another standard method: Applying the Euler substitution $$\sqrt{x^2 + a^2} = -x + t$$ transforms the integral to …
