How to answer the derivative of mathematics college entrance examination
The examination of derivatives in college entrance examination mathematics is usually a minor issue and a big one. First of all, we should memorize the formulas and rules of derivation of basic elementary functions, make clear the geometric and physical meanings of derivatives, and calculate simple definite integrals (we need to know the direct method and geometric method). The common type is the equation for finding the tangent. It should be noted that if a point is known to be on a curve, it is necessary to directly derive the derivative, and the slope of the tangent at this point is the derivative of this point, and then write the formula of the point inclination of the tangent. If the known point is not on the curve, we need to set it. Finding the coordinates of the tangent point can solve the problem. To solve big problems, there are common problems such as finding extreme value, maximum value and monotonous interval. , and the values of the parameter ranges derived from it. If this piece is not skilled, mark the definition domain of the function first, and then find out the derivative function accurately. Find extreme value, maximum value, monotonous interval, etc. Take a good look at the examples in the textbook. Many other problems can be solved by using equivalent transformation and constructor, such as the proof of inequality. The exam is coming. Take a good look at the similar problems you have done. Finally, I wish you to be the first!
