sumptaTRWBW: http://rafb.net/p/6IWFtj83.html is my work
TRWBW: the law of cosines is the next chapter in my book
TRWBWsumpta: sin(180-x)=sin(x)
sumpta: but not sure what you are doing here, let me look again
WILDSTYLEHi.
thermoplyaeWhat happened to all your caps?
WILDSTYLESomething seemed a bit off!
sumptaTRWBW: ah, I figured it out. .441035 corresponds to two degrees, one being 26.17 degrees and the other 180 - 26.17
TRWBW: the latter allows me to get the proper degree measure for gamma in the smaller triangle
TRWBW: which allows me to find the smaller distance
TRWBWsumpta: yeah
sumpta: if you look at the picture, the triangle made by the sun and the two potential positions of venus is isoscelles, so the interior angles are the same. another way to see why the two gammas are 180-x of each other

CecenCan a TI92 do anti-derivatives?
masqueradeCecen, yes
CecenExplain? :]
masquerade2nd-7
CecenOh crap, I didn't even notice
masqueradeits also under the Calc menu
MultiplyHi, I've got 400 points from 0 to 400, and another 100 points, from 100 to 200... If 100 is in point 0, and 200 in point 400, how do i find out where point 150 is in? I know it would be in point 200, but how do I calculate it?
Anyone?
CecenO-o
I don't understand.
MultiplyTake a look at this: http://juhp.dk:82/andet/bmi/bmi.php
What I wan't is to make point 0 to be showing as 100, as the lowest value, and point 400, to be shown as 200... Currently, it's counted as pixels, means this char is 400 pixels high.
The problem is, that the original pixel points, the min value, and the max value, can be changed dynamically.
CecenYou mean it's like the window on a graphing calculator? You want to change the origin/scaling?
MultiplyKind of, yes.
CecenSo originally, the points are between 0 and 400. You want to scale all the points down, so they're in 100 and 200?
MultiplyYes.
CecenAre you programming this?
MultiplyYup.
CecenC++?
MultiplyPHP
CecenNo idea how to use PHP, but:
MultiplyIf I could get a function or such, it'll be easy to do.
CecenActually I'll private you it
MultiplyOkay.
CecenIs the original 400 and 0 static or dynamic?
MultiplyDynamic
