AI Thread Summary
The square in the discussion has an area of 49 m², indicating each side measures 7 m. The red rectangle has a circumference of 16 m, prompting a calculation to determine the dimensions of the green rectangle. The four rectangles within the square vary in size, complicating direct measurement. Participants are encouraged to deduce the green rectangle's circumference based on the provided information. The discussion emphasizes logical reasoning rather than visual measurement.

The AREA of the square in the link above is 49m^2 and consists of, as you can see, 4 rectangles and 1 square. If the red rectangle has a circumference of 16m, what's the circumference of the green rectangle?

Maybe I should add that the 4 rectangles are not of the same size and you can not measure in the picture to get to the right answer.

I've reported this post, so it should be sent to the appropriate section soon. In the meantime, let's take a look...

Well, you have that the square is 49 m^2, which means that each side of the square is 7 m. We also know that the perimeter of the red rectangle is 16 m. What do you think you can imply from those two bits of data?
 

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...
