Topic: tangent in nbd of critical points
"Abnormal program termination " if say, we try and find the tangent of a non differentiable function at a point near (within about 0.2 units) the critical point .
Tangent of x^2/3 at 0.1
Sometimes it says that there is an "External exception EEFACE", instead of terminating.
Could anyone please explain what is going on?
