AI Thread Summary
The discussion revolves around solving a mathematical question depicted in a picture. It explains that there are 5 horizontal and 5 vertical lines, each representing a change of 2 in the x and y coordinates. To find the value of f(-4), one must move left from the origin by 4 units and then determine how far to go up to reach the graph of the function. The final step involves multiplying the number of lines traversed by 2 to obtain the function value. The conversation emphasizes the methodical approach to interpreting the graph for accurate results.

What help do you need? You can see that, since there are 5 horizontal and 5 vertical lines between the origin and "10" that each line represents a change of 2 in x and y. To find f(-4), start at the origin and go left(because it is negative) 2 lines (2 times 2= 4). Now go straight up to the graph of the function. How many lines is that? Don't forget to multiply the number of lines by 2 to get the function value.
 
Thank you

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...
