Subject trigonometry

It is easy to show, using elementary trigonometry, that the pyramidality coefficient of a given atom is a function of its distance, PD, from the plane defined by three substituents attached to this atoms. A simplified form of such a function may be derived subject to the assumption that the bond lengths, D, between the considered atom and... 

All branches of mathematics are interrelated, as may be seen from the school curriculum. Mathematics is the study of quantitative relationships. When such relationships are expressed in terms of number, that branch of mathematics is called arithmetic. When relationships are expressed in letters and numbers, with similar rules to arithmetic, the subject is known as algebra. Trigonometry studies relationships between angles. Geometry is concerned with size, shape, area, and volume of objects and position in space. 

Johann Heinrich Lambert (1728-1777), mathematician, physicist and philosopher, was a tutor for the Earl P. v. Salis in Chur from 1748-1759, where he wrote his famous work on photometry [5.2]. In 1759 he became a member of the Bavarian Academy of Science and upon proposal by L. Euler became a member of the Berlin Academy of Science in 1765. Lambert wrote several philosophical works and dealt with subjects from all areas of physics and astronomy in his numerous publications. He presented the absolute zero point as a limit in the expansion of gases and constructed several air thermometers. In 1761 he proved that v and e are not rational numbers. His works on trigonometry were particularly important for the theory of map construction. 

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.
