Hello, I am trying to write an algorithm to calculate the Least Squares Fit Line of a 3D data set. After doing some research and using Google, I came across this document, http://www.udel.edu/HNES/HESC427/Sphere%20Fitting/LeastSquares.pdf (section 2 in page 8) that explains the algorithm for...

Interesting that there isn't a defined epoch, only a synced time. Yes, I believe the lag is 13 seconds. Thank you very much :)

Hello, I've been searching all over for the epoch time of the WGS84 coord system. A GPS I'm using says its 06/01/1980, but I don't know if starts from 12:00:00 ET. Is there an epoch by definition or is it arbitrary?

Hello, Thank you very much for takign the time to help me out. This is an applied calculus 3 (multivariable calc) level problem. I have an answer, but it is nonsensical as the units are not in accordance with units of charge, C. Homework Statement Instructions: Use Gauss' Law for...

Yes there is one mistake i made when typing it: i did not factor out one of the g's. Typing mistake. Either way, thank you very much for you help. Im kinda ashamed to ask this type of question as I've taken physics for three years... but i have what i believe to be a momentary brain fart...

Wow, good point. however, choosing a direction is only useful for makign sure your signs are consistent. The algebra says its going the other way, can't that be possible? Or is it so late that I can't see clear enough? o.Ohmm...i shall ponder your statements.

Homework Statement Ugh, rusty on my Newtonian Mechanics and need to refresh. I picked out this problem in my book: Two boxes are on a 30 60 90 triangle. Box 1 is on the 60degree side and Box 2 on the 30degree side. The ramp has two different coefficient of static friction: u1 (for box 1)...

huh?

Thank you all for taking the time to help me out. Here's what I'm given: Homework Statement A solid door of mass M = 19 kg and width = 128 cm is hit at a right angle by a mud ball of mass m = 0.6 kg, which, as Fig. 10–44 shows, hits the door at the edge with speed v = 16 m/s and sticks...

Homework Statement The engine of an automobile requires 40 hp to maintain a constant speed of 78 km/h. (a) What is the resistive force against the automobile? correct check mark 1376.465N (correct) (b) If the resistive force is proportional to the velocity, what must the...
