im trying to write a program to determine target motion analysis, the problem I am having is determining how to get my computer to understand what side the 2 objects are on. here's an example. say I am a boat heading 300, so a little north west, and i have a contact on my right side, i need my...

hmm though string theory does predict messenger particles and the gravitron which may redefine this...

(5t-1)(25t^2+5t+1) i just distributed 5t-1 thought the 2nd part and got? this right way to do it? 125t^3-1 + 25t^2-1 + 5t

thanks guys

8 to the power of 0 is 0 right or is it 1? thanks thomsa

i think it was in a brian green book i read that said at the initial big bang era there was a moment where matter/energy became so dense that gravity actually became a replusive force? any way to harness that in a 5x5 coffee table cover? that would make a great conversation piece next to my...

if the magnet did stay attached to the iron bar, then wouldn't the iron bar itself float apart into little atoms? isn't the same force that holds the iron bar together partialy responsible for holding the magnet? I am not well educated but this is where you lead me :)

hmm ok you lost me /shrug

3z/2=z/6+4 so i x multiply and get 18z=2z+8 16z=8 z=1/2 this look right? thanks

circles... and pie ok so i found this site and I am learning about circles now :) http://www.mathgoodies.com/lessons/vol2/circumference.html it says pie is 3.14 which is what you get when you divide the outer measurement of the circle by the diameter (pie being 3.14 as per his homework)...

hmm i was close, thanks all my brain is fried I am done for the night. i thank you all and my son will enjoy life without the phone tomorrow for starting this at 10pm :) I am glad you all were kind enuf to help thank you for your time! thomas

hmm again 2(x-5)-(3x+3)<x-7 2x-10--3x-3<x-7 -1x-13<x-7 so -1x-1x is 2x<6 and that is x<3? whoray! did i get it! looks like it works!

division part i was referring to the < sign i remember them having to change for a reason, he says only if your dividing, i thought maybe it was for sign change but i think you answered me :0 let me look at last line again

2(x-5)-(3x+3)<x-7 2x-10--3x-3<x-7 -1x-13<x-7 0<6 i can't find the rules for when the sign changes my son is convinced that if you only divide then the sign changes to > i don't remember and he of course has his book in school :mad:

3-3(x-4)<4-3x 3-3x+12-4+3x<0 11<0 no solution direction are slove the inequality, and i think i got it right?! thanks thomas
