New mathematics is mathematics that is based on the laws of nature. Any physical law is an abstract mathematical law dressed in specific units of change. Mathematics is physics without clothes, physics is mathematics in clothes. Clothing (units of measurement) can be very different. Units of measurement are the key to understanding the laws of nature. Mathematics without units of measurement is an adult game of numbers according to the rules invented by mathematicians themselves. Today, mathematics is an ancient number game, similar to the game of chess, which adults play professionally. The mathematical theory of units of measurement, which will replace set theory in the future, has yet to be written.
All the secrets of the universe are written in the language of mathematics. If you want to understand math, always ask yourself the question: "How am I going to explain this to aliens?". This page contains links to my articles on mathematics, where I try to understand the answers to my questions. I get some kind of new mathematics, much wider and deeper than what we know. All these mathematical provisions and rules are not generally accepted, but reflect my personal view of mathematics.
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 (The Papers of Independent Authors. Volume 18 of p. 110111)  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 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 (The Papers of Independent Authors. Volume 19 of p. 7898)  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
