Free consultation for quick registration of junior college entrance examination: /xl/ For the candidates preparing for the math examination of junior college entrance examination, there are some test sites that we must master, because questions will be given in these places every year.

Test center 1: Calculate the limits of functions and sequences with classical tools.

Seven indefinite forms; Monotone boundedness principle, pinch criterion, Heine theorem

Test site 2: profound understanding, will use infinitesimal scale and infinitesimal scale.

Three application scenarios: limit itself, integral convergence and series convergence.

Test site 3: Deeply understand the definition of derivative and its geometric significance.

Derivative definition; Find the tangent normal; higher derivative

Test site 4: three logical questions

① Maximum value, median value, Fermat, Rolle, Lagrange, Taylor, Cauchy, integral mean value theorem (interval can be opened and closed)

② Inequality

③ Equation root (equation)

Test site 5: Geometric application of derivatives

Three-point (extreme point, inflection point, maximum point) amphoteric (monotonicity, concavity and convexity) line (asymptote) (one of the best curvatures)

Test Site 6: Existence Theorems of Indefinite Integral and Definite Integral

Test Site 7: method of substitution, integration by parts, Differential Method and Rational Function Integration Method (ideas)

Test site 8: Geometric application of integral

Test site 9: the concept of multivariate function
