Trigonometry mathematical equations

While it is desirable to formulate the theories of physical sciences in terms of the most lucid and simple language, this language often turns out to be mathematics. An equation with its economy of symbols and power to avoid misinterpretation, communicates concepts and ideas more precisely and better than words, provided an agreed mathematical vocabulary exists. In the spirit of this observation, the purpose of this introductory chapter is to review the interpretation of mathematical concepts that feature in the definition of important chemical theories. It is not a substitute for mathematical studies and does not strive to achieve mathematical rigour. It is assumed that the reader is already familiar with algebra, geometry, trigonometry and calculus, but not necessarily with their use in science. 

There is a near-mystical expression of equality in mathematics known as Euler s Identity, which links trigonometry, exponential functions, and complex numbers in a single equation ... 

Studies in mathematics must be beyond trigonometry and must include differential and integral calculus and differential equations. ABET encourages additional mathematics work in one or more subjects of probability and statistics, linear algebra, numerical analysis, and advanced calculus.
