Precal, Inequalities involving absolute value

AI Thread Summary
The discussion revolves around expressing the interval (-4, 4) as an inequality involving absolute value. The user correctly identifies that the interval can be expressed as -4 < x < 4 and concludes with |x| < 4. A response confirms that the final expression is correct and notes that the intermediate step of writing -4 < x < 4 is unnecessary. The conversation emphasizes clarity in understanding how to represent intervals using absolute values. Overall, the user receives validation for their approach to the problem.

Homework Statement



DIRECTIONS: Express the intercal in terms of an inequality involving absolute value.
PROBLEM: (-4, 4)
MY STEPS:
1: (-4, 4)
2: -4<x<4
3: |x|< 4 MY ANSWER
Is that correct? Is step 3 correct? The only reason that I included that part is becuase it says "Involving absolute value," but I am not sure if that is what the question is really asking. Please advise if you can. Thank you in advance.

hi name_ask17! :wink:

yes, that's fine :smile:

(and step 3 is obvious from step 1, you don't need step 2)​
 
lol. thanks tiny tim!
 

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...
