The dual song Yuxian function is a type of hyperbolic function. Triangular functions are divided into six types: Sin sin SIN, Yu String COS, Zhengli TAN, Yucai COT, Seda SEC, and Yu CSC. Then, similar, the hyperbolic function is also divided into six types: double -song sine sine, bispecular string, biscellaxia, biscellaxia, biscellaxia, and biscellaxia. The dual song Yuxian function is also one of them. The dwarf string function is recorded as cosh, or it can also be briefed as CH.
. The recurrence function
Puctable function refers to a function that uses plural as an independent variable and due to variables, and the theory related to it is the repeat function theory. The analysis function is a function of analytical properties in the complexity function. The recurrence function theory is mainly to study the analytical function in the plural domain.
The concept of plurality originated from the root of the pioneer. The negative number of square opens appeared in the root of the second and third algebraic equations. For a long time, people cannot understand this type. But with the development of mathematics, the importance of such numbers has become increasingly emerging.
The compound function theory mainly includes the content of single -value analysis function theory, Riemann surface theory, geometric function theory, retention theory, broad analysis function and other aspects. If the variable of the function takes a certain value, the function has a unique value, then this function solution is called a single -value parsing function, and the polynomial is such a function.
The variety function also studies multi -value functions. The Riemann surface theory is the main tool for studying multi -value functions. A curved surface composed of many levels is called Rikmann surface. Using this curved surface can make the single -value branches and branches of the multi -value function have a very intuitive expression and explanation in geometry. For a multi -value function, if it can make its Riemann surface, then the function becomes a single -value function on the Riemann surface. The Riemann surface theory is a bridge between the complex function domain and the geometric room, which can link us to the analytical properties of the most esoteric functions and geometry. At present, research on Riemann has a relatively large impact on another mathematical branch topology, and gradually tends to discuss its topology nature.
