Transcend function
In the field of mathematics, the transcendental function is opposite to the algebraic function, which is a polynomial equation that does not satisfy any function of a polynomial equation, that is, the function does not satisfy the polynomial of the variable itself. In other words, the transcendental function is a function of "out of" the algebraic function range, that is to say the function can not be expressed as a finite number of additions, subtractions, multiplication, division, and prescriptions between the argument and the constant. Strictly speaking, the parsing function for the variable z is a transcendental function if the function is independent of the variable z being algebraically independent. Logarithmic and exponential functions are examples of transcendental functions. The term "transcendental function" is usually used to describe trigonometric functions, such as sine, cosine, frontal, residual, truncated, positive vector, semipotential, and so on. Non-transcendental functions are called algebraic functions. Examples of algebraic functions are polynomials and square root functions. The indefinite integral operation of the algebraic function can produce the transcendental function. If the logarithmic function is in the study of the area surrounded by the hyperbolic angle, the reciprocal function y = ...
