Best ResponseYou've already chosen the best response.1x > x if x>0, or x if x<0

Best ResponseYou've already chosen the best response.1lol that's the mathematical description. in layman terms, if x is positive, like 4, then the absolute value of it is 4. if x is negative, like 5, then the absolute value of it is 5.

Best ResponseYou've already chosen the best response.0His mathematical description was a great answer for your question.

Best ResponseYou've already chosen the best response.0i know if i have x the solution is x=x that i know. my question is, how do you arrive at that conclusion... proof?

Best ResponseYou've already chosen the best response.1it's the definition. the proof is the first line i gave you. the mathematical description.

Best ResponseYou've already chosen the best response.0It's only x if x is positive. It is x if x is negative. It's one of those things that is so simple that it becomes tricky again. Say we are looking for x and x is 4... the answer is 4... but from the perspective of the original x, the answer is (4)=4.

Best ResponseYou've already chosen the best response.0google: "The magnitude of a real number without regard to its sign" i don't see that in ur description/definition/proof.... there's nothing related to magnitudes :/

Best ResponseYou've already chosen the best response.0I've never seen a more rigorous proof than the piecewise description given by @Shadowys . The literal meaning is: distance from the origin.

Best ResponseYou've already chosen the best response.1i.e. that's the layman terms. also, i.e. that's in terms of vectors. 4>4 2>2 x>x, for x>0

Best ResponseYou've already chosen the best response.0i don't think it's enough to settle with x=x, z=z ...

Best ResponseYou've already chosen the best response.1x > x if x>0, or x if x<0 this is the definition. in fact, it's called the absolute value function. that means it must be like that. MUST

Best ResponseYou've already chosen the best response.1there is no why in this. it is defined that way. the reason you're learning this because this particular function has importance in geometrical analysis.

Best ResponseYou've already chosen the best response.0let's just say there is a why. there's a reason for everything, if not i could just make my own math rules and say everyone MUST follow that rule.... unless u don't know the answer to the why in this... :/

Shadowys

Best ResponseYou've already chosen the best response.1yes. you can make your own rules, if they have an importance in something and if they conform to the original rules of mathematics.

Best ResponseYou've already chosen the best response.0well i'm still not satisfied with the given answer.

Best ResponseYou've already chosen the best response.2if x<0 then x is negative...so x is positive thus x=x

Best ResponseYou've already chosen the best response.0@Shadowys would you say that y+1=y+1?

Zarkon

Best ResponseYou've already chosen the best response.2if \(y+1<0\) then \(y+1=(y+1)\)

Best ResponseYou've already chosen the best response.0what's with the magnitude mentioned in the definition by google?

sasogeek

Best ResponseYou've already chosen the best response.0magnitude is distance... right?

EulerGroupie

Best ResponseYou've already chosen the best response.0From a linear geometric perspective, yes. If we are talking about pressure, for example, not really.

Best ResponseYou've already chosen the best response.2the absolute value of a number is its distanceto the origin

Best ResponseYou've already chosen the best response.0okay now this makes more sense than the earlier explanation/definition... thanks :)
