Okay, today i'm going to show you what is slope by curve or by the graph.
00:10
So there are two points here, as we show here.
00:14
Here is p1 and here is p2.
00:20
So when we calculate the slope, something is very easy.
00:26
What is slope? the slope is the tangent line.
00:31
For example, we have some, we have some.
00:35
We have a curve here like that, and this one is the slope.
00:42
So this one should be perpendicular to the curve just in this point.
00:51
So, but how can we calculate the curve? because each point may they have a different slope...
