What are the symbols of mathematics?
The square root of symbolic meaning I - 1 f (x) the value of function f at the independent variable x exp (x) the exponential function value at the independent variable x is often written as the x power of ex a ^ x a; the rational number x is defined by the inverse function. The inverse function ax of LN x exp x is the logarithm of a ^ x logba with B as the base a; blogba = a sin (x) is defined by the inverse function
