lim1/x-lim1/y=0? when both x and y are going to zero

OpenStudy (anonymous):

no. if x are going to from negative and y are going from the positive, the answer is not zero

OpenStudy (anonymous):

OpenStudy (anonymous):

if they all from the positive then it's zero?

OpenStudy (anonymous):

@eaglewod i think so

OpenStudy (anonymous):

why is that can you prove it ?

OpenStudy (anonymous):

THIS IS NOT ALWAYS BEING ZERO. THIS IS DEPENDENT THE DIRECTION WHERE X AND Y GO. SO PLZ ATFIRST TOLD ME WHAT THE DIRECTION. IN THIS CASE WHEN THE DIRECTION BOTH ARE FROM POSITIVE OR BOTH ARE IN NEGATIVE DIRECTION THEN IT IS ZERO,

OpenStudy (anonymous):

and the prove?

OpenStudy (anonymous):

any prove..except the symmetry

OpenStudy (anonymous):

@eaglewod can u draw the curve of (1/x)

OpenStudy (anonymous):

so x,y both from positive? then the result must be zero?

OpenStudy (anonymous):

no i am not told u draw the graph in 2 dimension, u draw it in one dimension because u study in sets in real number system.
