1 after 0
gaurang5:
but can you please explain it
there is a sharp point at 0 hence there can be drawn an infinte tangents at that point like a needle suspending a scale on its tip before 0 it is diffenetiable and equals -1 to the right of zero it is differentiable as it is +1
the graph of |x| is a V shape
why it is not diffentiable at 0
please
because you cannot draw a single unique tanngent at that point
why
you can suspend a scale in the tip of a needle in any angle provided you balance it,if there is no unique tangent thereis no diff
thank you it really helped me
;-)
