The derivative of a function y = f (x) at one point x = x0, is equal to the value of the trigonometric tangent of the angle formed by the geometric tangent to the representative curve of y = f (x)at the point x = x0, ie the derivative is the angular coefficient of the line tangent to the graph of the function at the point x0.
The derivative of a function y = f (x) can also be represented by the symbols:
y ', dy / dx or f '(x).
The derivative of a function f (x) at point x0 is given by:
