can't we check direct differentiability, if function is differentiable then it is also continous,isn't it? Reply

please reply. if we're talking about differentiability, is it always x-1 that we should use as denominator? Reply

Will you please teach concept of precise limit

this channel is dying

hey, please, teach us partial differential equation and Differential Geometry!

He solved the problem quite easily and it helped me grasping the concept.

good job doing it the long way

Thanks
