Complex trigonometric function . In Mathematics and, more specifically, in Mathematical Analysis are the trigometric functions whose arguments and results are complex numbers . It is based on the relationship between the trigonometric and exponential representations of complex numbers. It …
One of the fundamental concepts of mathematical analysis is that of limit, and in the case of a function it is to calculate the limit when the nearby points approach …
The concept of differential is linked to those of differential function and increase of the dependent variable, at a point in the domain of the derivative . Summary [ hide ] 1 Definition 2 Accuracies 3 Approximation …
Triangular inequality . This is the name of one of the characterizations in the axiomatic definition of distance and then speaking of metric space. Similarly when defining a norm [1] This property also serves to characterize …
Number e . It is one of the most important real numbers next to 0, 1 and pi. Obtained by a new resource in the mathematics of motion: limit of a sequence. It is an irrational and transcendent number , …
Measure of a set . Denote a measure of an interval (a, b) , where a <b is its length ba. Let H be an open set bounded by the line. There is a proposition …
Construction of real functions . In mathematical analysis , mainly (even in complex analysis), from the elementary functions, by means of rational operations and composition of functions, other new real functions can be constructed, …
