For example, to put of a negative number, you have to add π to the answer that you get (or 180° if in degrees); this is because arccot come from Quadrants I and II, and since we’re using the arctan function in the calculator, we need to add π. I am attempting to find a way around this but it is a function of the program that I use to convert the source documents to web pages and so I'm somewhat limited in what I can do.

That's a good question to explore with your students. It beautifully illustrates that formulae of the form asinx + bcosx = c are really just a special case of a more general fact: the combination of any two sine waves with different phase *always* results in a third sine wave whose amplitude is found (as can be seen above - the purple arrow) by means of a vector sum.

This book helps students recognize algebra as a natural extension of arithmetic. by John Radford Young - Wm. Lots of help is available for teaching advanced math. Whatever the subject there is a purity point of view and an issue with substantial numbers. Note also that when the original functions have 0’s as y values, their respective reciprocal functions are undefined (undef) at those points (because of division of 0); these are vertical asymptotes.

The sum of the angles of any triangle is equal to two right angles. From which he derived the half angle and multiple angle formulae. [See Note 6 below] While many new aspects of trigonometry were being discovered, the chord, sine, versine and cosine were developed in the investigation of astronomical problems, and conceived of as properties of angles at the centre of the heavenly sphere. The Chinese were the most accurate observers of celestial phenomena before the Arabs. "Oracle Bones" with star names engraved on them dating back to the Chinese Bronze Age (about 2,000 BCE) have been found, and very old star maps have been found on pottery, engraved on stones, and painted on the walls of caves.

Trigonometry is a branch of applied mathematics concerned with the relationship between angles and their sides and the calculations based on them. When each operation takes a nontrivial amount of time (and is prone to a nontrivial amount of error), a procedure that lets you convert multiplication into addition is a real time-saver, and it can help increase accuracy. Content of the second semester will vary from year to year; possible topics include class field theory, arithmetic geometry, analytic number theory, and arithmetic K-theory.

The use of sine was then adopted by Arabic mathematicians, later translated into the Latin word Sinus, literally meaning half-cord. Bill Engvall recounts a time that his preteen daughter came to him for help with her math homework: One talking Barbie doll would say, "Math class is hard!" The program also outlines a brief history of surveying instruments, from the dioptra of ancient times to orbiting satellites of modern times. To the first of these difficulties there can be but one solution.
