Okay, today i'm going to what is a slope.
00:04
Here in the question, so if we have a curve here, here is the curve and the slope is the tangent line for each point.
00:19
So in this case, if the point is here, the tangent line should be like that and should be perpendicular to the curve and we use the delta y divided by delta x to get the calculate the slope and let me go back to the question.
00:40
Here is the picture.
00:45
Yeah, the slope is like these and if we draw a line here, let me change the color.
00:56
So if we draw in line here and we perpendicular to there, okay, if we draw in line like that.
01:28
So here is delta y, here is delta x...
