Exponential graph




Exponential graph: The exponential functions are expressions in which the variable is in the exponent, with some restriction to the power lase. This type of function has the following formation law f(x) = ax or y = ax, where a belongs to the real ones with absence of zero, and a different one of.

The Euler number


Definition: In honor of Leonhard Euler, Swiss mathematician, the Euler number is a basis of natural logarithms. The number is an irrational and positive number, which logarithm at it’s base is called natural, e = 2,718 281 828 459 045 235 360 287, approximately.

Integral defined


(f continues in [a,b], F is a derivative in [a,b] )  
    (a - is the lower bound of integration;)
(b - is the upper bound of integration;)
  (f(x) - is the integrand;)


Integral defined: contains an initial value that is called the lower limit, and a final value called the upper limit.

The fundamental theorem of calculus is the basis of two central operations of calculus, differentiation, and integration, which are inverse each other, if a continuous function is first integrated, and then differentiated (or vice versa) returns to the original function.
