Yeah Iso, I was talking about the dot after \right, actually
Thanks for explanations guys !
It adjusts its format according to the brackets,paranthesis, etc according to the size of the expression contained within it.
For example:
Without \left and \right
If you type [\frac{\frac12}{\frac12}] = 1 you get
The square brackets are small compared to the expression inside and they look ugly
However with \right and \left
If you type \left[\frac{\frac12}{\frac12}\right] = 1 you get
The square brackets are now properly reformatted and looks nice.
I myself am still trying to figure this language out, and I came across something that seems pretty useful to me.

Nice smilie !
If you want it to be the same size :
[tex]\big(-\frac 14,0\big) \cup \big(0, \infty\big)[/tex] (note that you can write \frac ab, when there is only one term in the fraction ^^).
[tex]\bigg(-\frac 14,0\bigg) \cup \bigg(0, \infty\bigg)[/tex]
I would say this is useful when one has some difficulties to remember that the left comes before the right
If
Then
and
How would you do qunitic integration?
That doesn't look very nice .
I think I would actually prefer
Ahh..ohh...symmetry

Which do you think looks better?
or
?
but range of LHS is -pi to pi and range of RHS is -pi/2 to pi/2.so this equation will be true if lies between -pi/2 to pi/2. This happens if cos(A+B)>=0 as its >=0 between -pi/2 to pi/2
so or
If x,y>=0 or x,y <= on squaring there will be no change is sign therfor on squaring we get
also if xy<0 but on squaring there will be again no change of equality sign and we will get
but if xy<0 and on squaring there will be change of equality sign and we will get
so finally we get
if
1) and
a)x,y>=0
b)x,y<=0
c)xy<0 and
2) if
xy<0 and
but all the books that I have read say nothing about and . Are they not necesrary???
