AI Thread Summary
To determine the percentage reduction needed for a $20 coat to be priced at $5, clarity in the problem statement is essential. The discussion highlights confusion over whether the coat's price should be reduced by $5 to $15 or directly to $5. The proposed calculation of 25% is incorrect, as it misapplies the formula for percentage reduction. A clear explanation and correct calculations are necessary to solve the problem accurately. Understanding the intended final price is crucial for providing the correct percentage reduction.

You have the percentage the coat should be reduced to, instead of how much the cost should be reduced by.

No. 5*5 = 25, which is not the same thing as 25%.

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...
