I've corrected it Jan 16 asked Solving to get free falling coordinate as function of arbitrary coordinate Dec 30 comment eigen value of the gradient operator thanks a lot. That does it. I will try to reconstruct this for spherical coordinates.

Jul 23 comment This classic from euclid's elements, is it accepted everywhere? So its comes from the need of having a notion of "equality" which makes sense?

Jul 12 accepted How complex exponential converges and “sum of exponents” rule holds Jul 11 comment How complex exponential converges and “sum of exponents” rule holds Latex output is not correct in my browser, sometimes its ok, sometimes it not. Jul 11 comment How complex exponential converges and “sum of exponents” rule holds i know 2nd expression can be proved by binomial theorem, but failed to do so. and for the first one, if only the postulates of "complex arithmetic" is given, how it converges?
