<`m0> what if you want to fill a 2,1 matrix?
<JimDangle> anyways, i need to get back to what i came here for
<JimDangle> math stuff
<JimDangle> have a couple related rate problems -- http://bazzionline.com/math180wi07/assignment_11.pdf -- that im not sure if im going about right. so far im at 2xx' + 2yy' = 2dd'. and d = sqrt(23300) at 2 hours later
<srart> yeah. Is there a better forum for calulators?
<centrx> wait, are they related rate problems or are they related-rate problems ?
<JimDangle> uhhhhmm
<JimDangle> related rates?
<srart> `mo: http://www.codeproject.com/gdi/QuickFill.asp
<JimDangle> hmm
<JimDangle> isnt GetPixel SLOOOWW
<JimDangle> SetPixel is slow as a turtle, but i dont remember if GetPixel is as slow or not
<srart> Is he looking for a good explanation, or the best way?
<JimDangle> not sure
<JimDangle> anyways
<JimDangle> am i being retarded with my related rates problems
<JimDangle> i guess i did it right by finding d. then having d' = (2xx' + 2yy') / 2sqrt(23300)
<JimDangle> i mean it wanted the rate of change in distance between the two cars 12 hours later
<JimDangle> that seems reasonable to me
<srart> 2 hours later
<JimDangle> yeah 2
<JimDangle> i keep saying damn 12
<JimDangle> i didnt even go to class for this which kinda sucks
<JimDangle> i put sleeping ahead of a lot of things
<JimDangle> so the unit for the rate of change in distance would still be miles/hours wouldnt it
<srart> your answer about 152?
<JimDangle> for d?
<srart> yeah
<JimDangle> yeah
<JimDangle> its sqrt(23300)
<srart> yep
<JimDangle> i put d' = (2xx' + 2yy') / 2sqrt(23300) miles/hour, but im not sure if he wants the unit or not
<JimDangle> or if that unit is even right
<srart> yes, that is the rate of change
<JimDangle> hot
<JimDangle> thanks for checking it
<srart> your not expected to do this in polar trig crap right.
<JimDangle> not sure
<JimDangle> i dont think so though
<srart> change of angle between, and use that to solve, it would be ugly.
<JimDangle> oh that problem
<JimDangle> about to start it now
<srart> Your in calc right.
<JimDangle> yeah calc 1

<srart> http://www.calc101.com/ password 711560
<JimDangle> cool
<JimDangle> i need to get a math tool thing
<srart> good stuff, and will help in calc 2 (I don't think you'll need the password til then, save it in your email)
<JimDangle> i had maple, but then i put vista on and forgot to save maple
