im not working on slopes

4. JakeV8

Any chance this is probability related?

5. JakeV8

It is sometimes read as "x given y"

like the probability of me getting wet (x) given that I am walking in the rain (y) P(x|y) = 1 in this example

8. sasogeek

i'm trying to understand the concept of proof by induction and the given example states something like this \(\large 5|(n^5-n)\) ... i just want to know what that notation means. and hailey i'm in college :)

9. JakeV8

I'm not sure, then... my answer doesn't make sense for that example... sorry! I'm interested in the answer though!

i know when you're stating truth sets or solution sets, it is usually stated as x|solution with respect to x and read as x such that solution with respect to x. I'm not sure what this is though

11. JakeV8

Sounds reasonable,but I'm afraid I'm no help...

Yah it means "such that" Although in the example you gave, that might have been umm the divisor thing. Example: 5|15 --> "5 divides 15" or 15=5*c

o.O ohh sorry i dont no this math xD im in 8th gradee

14. zepdrix
