Natural numbers are determination - variation on a theme determination of natural numbers.

Integers determination - continuation of theme of mathematical determinations.

Transformation of trigonometric functions is a rule of direct corner - very simple rule of change of the names of trigonometric functions.

About symmetry of mathematical actions - whatever was talked by mathematicians about priority and secondaryness of mathematical actions, symmetry of mathematical actions is a fact that can be not noticed, but it is impossible to refute.

A theorem of Khyzhnjak about parallel lines - is formulation of theorem without proof.

Decision of the undecided equalizations - if to want, then deciding is possible all, if there is though some sense in written.

Bases of mathematics - under such name I wrote the cycle of reasons about mathematics, that is given below:

- basic axioms of mathematics

some concepts of mathematics

some concepts of mathematics are continuation

relativity is in mathematics

number line

relativity of concept is "Any Number"

units of measurements and mathematical actions

quantity as basis of mathematics

change of corner of scale

trigonometric dependences of corner of scale

space evolution

multiplication and division by zero

More deep consideration of bases of mathematics:

Why is a zero not a number?

Law of cosines for perimeter

Law of cosines in general

In 2016 I published the following works:

Measurement of plane angles ("The Papers of Independent Authors" Volume 36 of p. 43-45)

Trigonometric functions in a rectangle ("The Papers of Independent Authors" Volume 36 of p. 46-69)

- Trigonometric functions in a rectangle. Annotation. Short analysis of trigonometric functions.

Transformations of a triangle to a rectangle. Angular symmetry in a rectangle.

Three main types of trigonometric functions.
