Homework Statement I have to integrate http://img69.imageshack.us/img69/4259/integral1.gif The Attempt at a Solution This is how I did it [PLAIN]http://img338.imageshack.us/img338/5508/integral12.gif wolfram says it is supposed to turnout like this...

hi Homework Statement I have to prove or disprove the following statements: 1. Let B be a square matrix nxn. Then there must be an Invertible A such that AB is an upper triangular matrix. 2. Let A be a square Invertible matrix nxn such that the sum of all the entries in each row is...

Thanks for your answers but it is just a bit fuzzy yet. Does anyone have a link to an article or some kind of resource about Coriolis?

Hi, all Homework Statement A plain is flying at a constant velocity v=3 km/s at a constant height above the surface of the Earth, from point A on a Latitude which forms an angle of 20 degrees with the North Pole, to point B which is 5 km north to A. Assuming that B is very close...

O.K. It's a bit more clear now. But where does the Coriolis Effect come from then?

Hi, everyone We were told in class that the Coriolis Effect is due to the change in the radius in circular motion. But an objtct moving with constant velocity on the edje of the circular system, like on the equator still experiencing Coriolis force, because the cross product 2wXv is not...

Got it now, thanks!

O.K Iunderstand the technical side of what you are saying Av=0, but the equation you get is 0w=0. How can this have any meaning?

Do you mean that if we assign w=t a general solution could be V=(0,0,0,t)?

Hi, Homework Statement I was given a linear equation system of the form Ax=b where x=(x, y, z, w), I reduced (A|b) to its canonical form which is this: Homework Equations The Attempt at a Solution At first I thought that this means that there is an infinite number of...
