Note: absolute value is squared, not multiplied by 2.

ganeshie8 · Answer

there is no need for absolute value as the stuff inside is never negative

ganeshie8 · Answer

Proabbly, only the tool devoloper knows the real reason.
the tool is not smart enough to give you something more meaningful

ganeshie8 · Answer

wolfram has no problem in interpreting this correctly http://www.wolframalpha.com/input/?i=y+%3D+%5Cfrac%7B%5Cfrac%7Bx%5E2%7D%7By%7D%7D%7B%5Cleft%7C%5Cfrac%7Bx%5E2%7D%7By%5E2%7D%5Cright%7C%7D

I was just fixing to ask 
why is it showing a graph that looks like sprinkles on icecream?

ganeshie8 · Answer

lol looks it is trying to sprinkle the entire plane or something...  the equation is an identity so idk how the tool interprets. lets try other identities like x=x or sin^2x+cos^2x=1 and see what it outputs maybe..

I tried to graph y^2=y^2 on it but it just says true

geerky42 · Answer

It just say it is true, I guess what I inputted is too complicated for tool to detect that it is identity.

geerky42 · Answer

I thought it is complicated equation, until I rearrange the equation. Don't know why I quickly came and asked you guys. At least we get to see something interesting....

ok what if it doesn't understand compound fractions

freckles · Answer

I tried to graph y=x/(x/1) by nothing

ganeshie8 · Answer

Looks you nailed the possible reason! see https://www.desmos.com/calculator/p71mx55qkg

freckles · Answer

oh no it showed

ganeshie8 · Answer

it has some issue with compound fractions!

ikram002p · Answer

y^2/x^2=|y|^2/|x|^2
it ovc there is no graph

ikram002p · Answer

its like saying graph
0=0
1=1
2=2
... ect

ikram002p · Answer

xD it have all R as Domain all R as range

ikram002p · Answer

so dont blame the little calculator any graph tool would do the same , even if u graph it on ur own

ganeshie8 · Answer

poor calculator, it should detect that as an identity before attempting to plot all points like crazy lol

ikram002p · Answer

haha lol
