The slope is derivative, the slope is positive, and the derivative is greater than 0; The negative slope is less than 0. For the slope of the curve function, the slope will change and the derivative will also change. If the slope is constant, the derivative value is not displayed. For example: y=5x2 slope is 5, so the derivative is 5. Because they are all 5 in the definition domain, the derivative image is a constant function: y = 5.

If the slope changes constantly, then the slope is equal to the slope of the tangent passing through the point (should you understand? )

The first section: the problem of climbing a mountain-in fact, it is the problem of slope.

Part II: Memory derivative formula.

Pay attention to understanding

It will be easier to climb step by step in the future, I believe you! ! Be sure to understand! ! In the future, it will be definite integral and calculus, that is, using derivatives to find the area, which is very simple!

Pay attention to the last point: think positively in class and don't be distracted. .

By the way: how can I learn 2-2? Today is Friday. I just learned to play the first chapter.

We are both sophomores, math version B, right?

Believe in yourself and work hard for it!
