hi guyz,(adsbygoogle = window.adsbygoogle || []).push({});

im in skul and came across a small problem while solving some geometry questions

incase of cartesian plane..

slope of x axis is tan(0)=0

and slope of y axis is t(90)=infinite/not defined

so when we mutiply both the slopes we are suppsed to get -1

( from m(1)*m(2)= -1 ,, if m1 is 90 degrees to m2)

wat i hasd in mind is..are the x axis and y axis actually perpendicular..or they seem to be pependicular, i.e approaching to 90 degrees..

im sure there is some concept of limits over here...can u plz tell where am i wrong..
