Knowledge summary 5

English:

Memorize 100 words, one hundred words cut with supporting data, who are familiar with its meaning, practice listening, reading and made two.

C Language:

Review variable storage class, the mixing operation.

High number:

Learn derivative concepts:

Linear motion speed:

Understand the function of position, speed, average speed, instantaneous speed.

Tangential issues:

Learn circle tangent, tangent, tangent slope angle.

Learn the definition of a derivative, change the function of the rate of the problem, the guide function.

Pilot use of definition of the function.

Unilateral Derivative:

Left Derivatives: The function f (x) in the left limit X0 is called the Left Derivatives.

Right derivative: The function f (x) at the extreme right of the X0 is called the right derivative.

Left and right derivative derivative referred to as one-sided derivatives.

If the function f (x) can be turned in the open interval (a, b), and the two derivative functions are present, say f (x) in the closed interval [a, b] can be turned on.

Understand the geometric meaning of derivative:

Learn tangent equation.

Normal: through the tangent point and the straight line perpendicular to the tangent to the curve is called f (x) normal to the tangent point.

Functions can be turned and Continuity:

There are equal derivative of the function is present and equal to the derivative of the left and right derivatives.

If f (x) may be turned on at X0, then f (x) continuously at the reverse is not necessarily at X0.
