1, basic elementary function
Common basic elementary functions: exponential function, logarithmic function, power function and trigonometric function. Divided into finer points, namely inverse proportional function, linear function, quadratic function and transcendental function.
2. Derivatives
Many people say that derivative is difficult, but it is true that derivative is linked with an advanced mathematics. This is a transitional period. In fact, it is what we often call transcendental function, which is to solve problems by combining basic elementary functions.
3. Functional thinking
Functional thinking is a thinking strategy to solve "mathematics" problems. Since people used functions, after long-term research and exploration, the scientific community generally has a kind of consciousness, that is, "function thought." When using this thinking strategy to solve problems, scientists found that they all have the same property, that is, the connection between quantification and variables.
