the first floor of a home has a floor plan with 3 rooms. basically, there are 3 squares, and you have to find an expression in standard form.
square 1: W=2x L=x
square 2: W=x/2 L=x/2
square 3: W=x-5 L=6

I have issued the warning of Tsunami 2 hours before it struck our Indian coast. It was ignored. We lost the lives of ten thousand innocents. To issue the warning I used a simple equipment quake alarm designed by me and my knowledge on earthquake and Tsunami. Because of the inferiority complex by our meteorological department they have not shown interest to find out the fact how it was possible for me when they failed to alert. To day Dr Chadha of National Geographical Research institute in Hydrabad has reported to news paper that it is not possible to predict the earthquake for at least another 50 years. In the absence of any reliable fore warning system the quake alarm like the one designed by me will be the safest equipment at least for the time being to save the life of the people. This instrument will alert the people at the starting of earthquake before the people feel it. People can move to a safer place.

I heard that somewhere (possibly, in England) you can make an analysis to identify Dschinghis Khan's paternity. He had more than 40 children and at least two times more grandchildren. Obviously, he had a lot of offsprings now. May be I'm one of them! And may you are!

i am just double checking on this

i am taking the integral of

(e^-t)<3,t,sint>

so it should be the integral of

3(e^-t)i + t(e^-t)j + (e^-t)(sint)k
right?

and that means the integral of the k part is gonna suck right?

hopefully i missed something.

What is life? Do you think that living things are wholey physical things, just chemical reactions? Is life something that can be completly understood using the laws of physics and chemistry or is there more to living things? Do you think there is something like a vital force or a soul that separates living things from non-living things? Is it possible that even if we knew everything there is to know about the physical and chemical nature of life forms that we would still need something like a vital force to fully describe and understand them?

Lol, I don't have time to explain to everyone why they are horrible things to use... But maybe somone else will be kind enough to enlighten you :-)
Any comments? I'm sure I will recieve a fair share of insults, they do not bother me though, since they are coming from people who can't even control their emotions over a scientific idea lol, sad.
