Answer 1

Topic: Application in function research of derivative

Summary: The derivative is the important concept in calculus. Application of derivative quite extensive, theory and method of it see through all field to reach real world. And in mathematics, the main target that the derivative studies is the function, in studying the sex attitude of the function, seem extremely important too. Its application shows: Utilize the derivative to ask the tangent line equation of the curve; Utilize the derivative to ask the dull block of the function; Use the derivative to prove or ask the inequality of solving; Utilize the derivative to ask the extreme value of the function and be most worth.
Keyword: The derivative, tangent line equation, the inequality, dull block, extreme value

Answer 2

Title: derivative function in the study of

Abstract: derivative calculus is the important concept. Derivative of a wide range of applications, its theory and Cantou way to the real world in various fields. And mathematics, derivative research is the main target function, the study of sexual function in the state, is also extremely important. In its application performance: the use of derivatives for the tangent equation, using derivative function for the monotonous interval; use of derivative that inequality or for the use of derivatives for the function and the most extreme values.
Key words: derivative, tangent equation, inequality, monotone interval, extreme.
