Favorite Integral: Gaussian or ∫(sin x)/x?

[FrancisD]

I do love the Gaussian Integral. It's a beautiful one for sure.

Also though,

∫(sin x)/x (over all space)

is a great one.

\int e^x dx

Genius.

 

[Ivan92]

\int e^x dx

Genius.

You would have that as your favorite integral xP

Hmm my favorite integral...it depends what I feel like doing...lol! I'll edit this later and think about this further.

\int\frac{1}{\text{cabin}}dcabin \ = \ ?




\text{log cabin plus sea}

The one I already solved :P

And just to top it of

\int \sin(\ln x) + \cos(\ln x) dx
\int_{\mathbb{R}} \sin(x^2) + \cos(x^2) dx
\int (2x^2+1)e^{x^2} dx
\int \frac{x^2}{x^2+4x+8} dx
\int \frac{x e^x}{(1+x)^2} dx
\int \frac{x^{29}}{\left( 5x^2 + 49 \right)^{17}} dx

But yeah, the list of my favourite integrals changes from day to day so :p
