LMFAO.
I included Y by using a symbolic Solve[ ] function.

4 answers, all over a page long. O.o

Trying a reduce function... I have the odd feeling this is either going to crash my computer or just not work.

Sometimes, the best results are done with a pencil and paper.

It's down to 4 lines now, using the most basic simplification algorithm is has.
Using the full one now... zzz.
Hmm came up with something pretty long, but reasonable looking.

Luckily the 4 answers are just + or - versions of each other for the different square roots. I just need to plug some stuff in and see which are the one(s) I want.

EDIT:
I got
the same P = with those assumptions

As well as:

All that's left is to find the values to plug into it, huh? Well, good luck with that. I wonder how it derived that particular answer. The absolute part implies that it's getting rid of the root somehow, but damned if i know how.

H and V are just the individual components of the wind. Probably want to replace them with cos/sin of the wind angle, times wind power. Possibly times mobile wind resistance, too?

It ended up with Sqrt(( with every value inside squared. I defined them as real numbers so it converted to an Abs sign.
I'm going to check it by hand tomorrow to make sure it's right though. Took me a while to figure out the program's syntax and abilities, but learning Mathematica and the calculator are my main goals from doing this anyway.

I actually got a positive version as well. I will need to make sure I eliminate the correct one.

I missed something... M = Mobile power multiplier... what's that?
Some shorthand of the shot weight/speed?


If there isn't a shorthand for each bot's shot weight/speed, could one be made to make a formula shorter? Since each bot's combination of the two is unique?

M would be the shot speed referred to in the original post.

G would be the gravity, or weight, of the shot.

And I don't see how you would eliminate those constants to simplify further.

You can just write the formula "for turtle only" kind of thing I guess.

Assuming G=98 and M=230, wind=0
CODE
Power = ((7Sqrt(2))/115) * Sqrt(X_Dist_PX*Csc(ANGLE))


And ((7Sqrt(2))/115) = 0.08608256467...

But I doubt anyone can do csc in their head.

yeah, mezz gets what I mean.

Write the formula as it would appear if speed/gravity were known and fixed. Reduce it to the simplest variables:
Distance/Vertical Distance/Angle/Power/Wind/Wind Angle/

All other stuff could be presolved and then made into a slightly easier formula. Prolly this is spoonfeeding a bit much but I like tidy things.

Then offer a different shortened version with those same variables for each bot.

I'm working on it :D
I have lots of memory on my calculator, but very little power so I am trying to get a bunch of reduced formulas.

Quick noob check to make sure I don't screw something fundamental up:

W_Power*Sin(Wind_Angle)=Horizontal Wind
W_Power*Cos(Wind_Angle)=Vertical Wind

Right?
EDIT: never mind, duhhhh.

I haven't used trig in a while :Z

Well, seeing as how I have a Ti-83, all I basically did was make a Program that had the formula while inputting X,Y,Z,(Theta) values.

I use the formula above for power, and a few windcharts and voila, external aimbot =]

X= Distance (Pixels)
Y= Angle of Shot
Z= Wind Power
(Theta)= Wind Angle

Why do you still need windcharts? This formula accounts for wind, I think.

Well, I just took the original equation (The one posted, plugged into the Calc) and just sort of made my own system of equations from there.

I think most of the posts here are to simplify equations with wind factored into them.

dry.gif , dont work me,
IPB Image

i try with,
xdist = 26
wind = 0
angle = 89

in your formule i get -0.224515467254494 wacko.gif , and the true result is 2.25

what happend..???
P := (-1) *
Abs( G * xDist + V * xDist + H * yDist ) /
(
Sqrt(2) * M * Sqrt
(
Abs( ((G+V)*Cos(A) - H*Sin(A)) * (yDist*Cos(A) - xDist*Sin(A)) )
)
);

i got a question if i wanna find out some 0 angle powers for example nak 70 i tip in my ks calc 4*Sqrt((98*800*1.00)/(4*Sqr(205)*Sin(Rad(2*70)))) so i get power 3.4072218... but creedos 70 1 screen power is 3.36 where is my mistake? T_T

Pm a physics user. Is turtle all you need? I'll ask my buddy if he knows.
