Notation Help: Expression Evaluated From a to b

[sjwalsh]

Hi, I am writing a paper on Fourier Series and I am trying to write the following equation in the math window:

a sub n = 1 over %pi [ (x^2 over n) sin(nx) - int{(2x over n) sin(nx)dx} ]

But I need to have the [ (x^2 over n) sin(nx) - int{(2x over n) sin(nx)dx} ] evaluated from -π to π and I don't know how to do this notation since I'm not just doing an integral. Can somebody please help me out?

Thanks in advance,
Steve

What notation do you want to use?

An easy way is to put "x=-π" in subscript after the square brackets and "x=π" in superscript.

Note that if you put the command "left" before all the left brackets and "right" before all the right brackets they will stretch to fit what's between them. Also putting a space after each term will help ensure the equation is formatted properly.

For the whole equation you could use:

Brilliant Ed! Thanks for your help, worked perfectly. Fast too.

Gotta love open office
