I really with this Pre Calculus problem =[

AI Thread Summary
The discussion revolves around a Pre Calculus problem involving the sketching and graphing of four equations, with confusion arising from the notation used. Participants express uncertainty about the meaning of square brackets and the "I" symbols, which are clarified to represent absolute value bars. Suggestions are made to plot points by substituting values for x to visualize the graphs. One participant attempts to address the second equation, the square root function, by providing a link to a graphing tool. Overall, the conversation highlights the importance of clear mathematical notation in understanding and solving graphing problems.

sketch and graph
1. y= [x][/3] +2
2. y= squareroot x-3
3. y= Ix-2I
4. y= [y][/2] - 1

If you're not sure what the graph looks like, then just plug in some numbers for x, (x=1, x=2, x=3) and then plot the points. Then just connect them with a smooth line.
 
I don't actually understand your notation. What are those square brackets and "I"s?

I don't understand even one of these. What do the square brackets mean?

But I'll take a stab at (2) :-p

Yes what are the square brackets?
 
I think it's pretty straight forward, albeit bizarre notation. The brackets mean nothing, and the "I...I" are supposed to be absolute value bars "|...|".
 

Thread 'Finding the number of ways to arrange identical balls in a circle (3 different colors)'

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks

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...
