The result below is not very known:

Let f:I -> R be differentiable on the open (non empty) interval I. Then, there exists a subinterval of I where f is Lipschitz.

Actually I think this is true under a less rigid assumption. I think the conclusion remains true if, instead of full differentiabilty on I, we assume the existence of the Dini derivatives, that is, suppose that, for every x of I, f is differentiable at least at x+ or x-, not necessarily at both.

I solved this problem by hand and by calculator(pretty print is on so i know i typed it in correctly)

but i got a different answer doing it both ways

the problem is
triple integrate (y dz dy dx) where:
0 <= z <= 2-2x-y
0 <= y <= 2-2x
0 <= x <= 1

i got 4.4222
and the calculator got .3333

can someone tell me the right answer?

*maybe show some work if possible*
