This problem.

Forty one of this tour calculus eighth edition section two points.
00:05
Each lament represents derivative of some definition of some function.
00:08
After that summary states such an af and a in each case, the limit is each bridge is zero.
00:14
Of course, i know times the quantity piper's h plus one over each.
00:22
So we compared this limit with the equation with the equation to pour that narrative.
00:31
Um, that states the limited's each approaches zero the dirt is equal to the limit is h of purchases of a function f evaluated plus h minus, the function evaluated at a all right, all right, h now, through comparison, we suspect the function is co sign of x.
00:56
And we suspect that because first term here we'll each of these summer should be the function.
01:04
But the first term is directly the function evaluated at a plus each...
