hi guyz,
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 please tell where am i wrong..
