... it easy: 2dx/dt*d^2x/dt^2+2dy/dt*d^2y/dt^2= 2x*dx/dt*SQRT(x^2+y^2)+2y*dy/dt*SQRT(x^2+y^2) ==> d((dx/dt)^2+(dy/dt)^2) = some function of x^2+y^2 etc...
... These are the equations of a particle moving in a central (repulsive) r^2 force field. Maybe tetrakovsky means the quantity: E = (1/2)((dx/dt)^2 +...
hi thanx for help but I'm a physics student and lil slow in math, is there dt on the left side? and what kind of function will I be needing for the other...

Hi, From Geometry, congruence of two triangles is established by equality of corresponding parts of the triangles: Two sides and included angle SAS Two angles...
Cino is correct. Three pieces of information is a necessary, but not always sufficient, condition to completely determine a triangle. See Law of Sines...
Thank you for sending that link! I looked a ton of these sorts of things up on the net, but the one you sent was a lot better than the ones I found. I...
Hypotenuse Calculator - Can someone test my program? I just wrote a small VB app, its only 16 Kb, it lets you enter three known side lengths for a triangle...
Without seeing the program or your Excel worksheet, it sounds like you need to check your input before you apply the trig formulas. Specifically, you need to...
Hi, I took the liberty of changing the Subject line. The Romans said 2000 years ago, "Scientia potestas est." Lets see what we can do with a little knowledge. ...
If you only know two side lengths of a scalene triangle (but none of the angles) can you determine the third side length? I had been using this formula...
Ed, thank you! This is VERY helpful!!! ... From: Edward Moore <emoore06905@...> Subject: Re: [MATH for FUN] Hypotenuse Calculator - Can someone test...
Will this work Cino, if its a scalene triangle and where none of the angles is 90 degrees? ... From: cino hilliard <hillcino368@...> Subject: RE: [MATH...
I found this at the link below. Its supposed to let yo figure out side (b) of a triangle.... but I can't understand the last part of this.... where the "2ca...
Yes, This works for any angles a>=b>c and a+b > c. Here is another script that sorts and tests for a+b < c. angle(a,b,c) = { v=vector(3); v=[a,b,c]; ...
I've tried to incorporate all I've learned so far... but I keep getting weird errors and as far as I can tell all my formulas are correct? I've built a...

I haven't looked closely at this, but one problem I see with problem 2 is that 50 minutes does not correlate to 0.5 - use 0.833. Better yet, use 5/6. Ed ...
