What are the five basic functions of mathematics?
Basic elementary functions include the following:

(1) constant function y = c( c is a constant)

(2) power function y = x^a( a is a constant)

(3) exponential function y = a x(a >;; 0,a≠ 1)

(4) logarithmic function y = log (a) x (a >; 0, a≠ 1, real number x>0)

(5) Trigonometric functions: there are mainly the following six types: sine function y =sin x cosine function y = cos x.

Tangent function y =tan x cotangent function y =cot x secant function y =sec x cotangent function y = CSC X.

In addition, there are trigonometric functions that are rarely used, such as forward vector and complementary vector.
