AI Thread Summary

The discussion centers on evaluating the mathematical expression $\frac{m^2g^2-m^2}{ma+za}-\frac{zamg}{am+az+gm+gz}=-\frac{zma^2-z^2a^2}{ma-mg}$. Participants express skepticism about its validity, suggesting that testing with specific values reveals inconsistencies. Initial attempts to prove the equality lead to the conclusion that it is not true. The conversation emphasizes the importance of verifying mathematical claims through substitution. Ultimately, the consensus is that the expression does not hold true.

How could I show that this is true:
\frac{m^2g^2-m^2}{ma+za}-\frac{zamg}{am+az+gm+gz}=-\frac{zma^2-z^2a^2}{ma-mg}

Where does that expression come from? It doesn't look true to me. (Plug in a few values and see for yourself.)

yeah, it's not true...well, that makes it easy to show it's not true.

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...

Thread 'Making the denominator of a certain fraction real'

Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
