Mathematics in Senior High School is a book published by People's Education Publishing House, compiled by People's Education Publishing House, Institute of Curriculum Textbooks and Research and Development Center of Mathematics Textbooks. Including set and function, trigonometric function, inequality, sequence, complex number, permutation, combination and binomial theorem, solid geometry and plane analytic geometry.
Formula Formula "Set and Function"
1, content complementary set, power exponential pair function. Parity and increase and decrease are the most obvious observation images.
2, the emergence of composite function, the law of property multiplication, if you want to prove in detail, you must master the definition.
3. Exponential function and logarithmic function are reciprocal functions. Cardinality is not a positive number of 1, and 1 increases or decreases on both sides.
4. Functional domains are easy to find. Denominator cannot be equal to 0, even roots must be non-negative, and zero and negative numbers have no logarithm.
5. The tangent function angle is not straight and the cotangent function angle is uneven; The real number sets of other functions have intersection in many cases.
6. Two reciprocal functions have the same monotone property; The images are symmetrical with Y=X as the symmetry axis.
7, the solution is very regular, and the domain is replaced by the inverse solution; The domain of inverse function, the domain of original function.
8. The power function is easy to remember, and the fractional index is reduced; Keywords exponential function, odd mother and odd son odd function,
9. Even function with odd mother even son, even mother non-parity function; In the first quadrant of the image, the function is increased or decreased to see the positive and negative.
