[P.T.F.E]

can anyone help with stat pts of y= x2 -1 / x2

i have an answer but doesnt look right. please help.

 

[duy.le]

i drew the graph and its indicating that it shouldnt have any stationary points...

then i did it algebraically and found no stationary points either :O

i just got x=+- i.

yer i didnt get stat pts only a horizontal pt of inflexion at x =2 but i hav no idea???

 

[gurmies]

is it (x^2-1)/x^2 ?

 

[GUSSSSSSSSSSSSS]

by inspection no stationary points
as (x^2 - 1)/(x^2)
also equals
(x^2)/(x^2) - x^(-2)
which equals
1 - x^(-2)

defs no SP's

 

[gurmies]

Points of inflexion are stationary points?

 

[Pwnage101]

Points of inflexion are stationary points?

some can be, ala y=x^3 (ie at x=0)

 

[P.T.F.E]

is it (x^2-1)/x^2 ?

yep soz about my typo
