AI Thread Summary
To solve the equation h^2 + (π)r = K for r, the correct formula is r = (K - h^2) / π. There was confusion regarding the placement of parentheses, which is crucial for clarity in mathematical expressions. The initial attempt mistakenly suggested r = K - h^2 / π, which alters the intended meaning. Proper notation is essential to avoid misinterpretation. Clear communication in mathematical equations ensures accurate solutions.

This is correct if you mean r=(k-h^2)/(pi)

<br /> r=\frac{k-h^2}{\pi}

[edit] no e in pi... ;)

This is incorrect: you have written r = K - \frac{h^2}{\pi}, at least when read according to *standard rules*. If you mean that
r = \frac{K - h^2}{\pi} , then you need to use brackets: r = (K - h^2)/pi.

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...
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...
