hay,is there a fancy term for people that give injections?

#9952 Re: Help Me ! » Equations with parenthesis? » 2011-09-12 07:08:37

i know the proper term,but it sounds cooler when you say 'stab people and drag their blood',doesn't it?

#9953 Re: Help Me ! » Equations with parenthesis? » 2011-09-12 07:06:09

i wanted to say drag,but my mind was probably lost in thoughts.

#9954 Re: Help Me ! » Equations with parenthesis? » 2011-09-12 07:02:18

it sounds like a cool job.you get to stab people and drag out their blood.

hi guys

i have got a geometrical answer for two,and seems a little easier to do,and shorter to write,but maybe a little bit more complicated to understand:

in geometry class we learned that the minimum length in this case we could get by turning one pole around with symmetry,then connect the top of the inverted pole with the top of the other pole.where the poles intersect you will get the minima.

if you want to get the length of the wire you will see that it is a hypotenuse of a right triangle whose one side is the sum of heights of the two poles,and the other side is the distance between the two poles.

now to get a picture of what i mean check Figure 1:http://www.springerlink.com/content/n51 … 1&locus=66

if bob understood this maybe he could make a clear picture?

hi zee-f

everything is correct,but here's a little LaTeX tip:

when you want to write multiplication of two fractions it is best if you bring the multiplication sign in LaTeX tags:

what is even better is to use the LaTeX command for the dot that represents the multiplication sign,and the command is \cdot :

hi guys

is this correct for (3):

eg.  (5,6) - (6,6) - (1,2) where someone has joined at the other end.

first of all i know what a domino is.

next,i don't think that the statement in the quote above is legit. (6,6)-(1,2)?

last,i never heard of 3's and 5's,but if i am getting the rules correctly (6,6) would give you 4 points?

hi bob

i'm not sure i am getting this.

i would very much like to see Science and Linguistics here.but all of this could maybe mess with the main purpose of this forum(math).
