They can allow us to put a function in terms of one trigonometric function into terms of another. The most basic, and likely most common, identity is the Pythagorean identity, which states: While these three equations appear different, they are equal to one another , source: http://nickel-titanium.com/lib/fundamentals-of-algebra-and-trigonometry-study-guide. He considered every triangle as being inscribed in a circle, so that each side became a chord. While chords were easy to calculate in some special cases with Euclidean knowledge, in order to complete his table Hipparchus would have needed to know many formulas of plane trigonometry that he either derived himself or borrowed from elsewhere , cited: http://www.siaarchitects.com/?library/constructive-text-book-of-practical-mathematics-volume-iii. In higher mathematics the applications are similarly endless. For example, in Fourier theory one studies representations of periodic phenomena (sound waves, digital signals, etc.) as sums of trigonometric functions (sine and cosine to be precise). You need calculus to determine how things are changing. Understanding, for example, the rates at which drugs are processed in the body in the presence of other drugs might be an example http://nickel-titanium.com/lib/plane-trigonometry-by-s-l-loney. You do not HAVE to take it then if you are not prepared. But you will not be able to register for calculus until you have taken the test. How can you practice for the trigonometry placement test? The following topics may be covered on the placement test: Given the side lengths of a triangle, find the sin, cos, tan, cot, sec, and/or csc for a designated angle of the triangle. See problem #1 from the practice problems Given that a point (x,y) lies on the terminal side of an angle in terminal position, find the sin, cos, tan, cot, sec, and/or csc for that angle http://nickel-titanium.com/lib/algebra-and-trigonometry-instructors-annotated-edition. The key is writing down the diagram, which is shown at the right , cited: http://www.manonthemoon.es/?freebooks/student-study-and-solutions-manual-for-larson-hostetlers-precalculus-a-concise-course-2-nd.

For an accuracy equivalent to seconds of arc, four decimal places should be kept. The natural unit for angles in trigonometry is the radian, which is always divided decimally. Only when radians are used is the sine of an angle approximately equal to the angle for small angles. However, the radian is usually inconvenient in practical problems. Angles are often measured in sexagesimal time units in Astronomy, where 1h = 15°, 1m = 15' and 1s = 15" http://www.honeytreedaycare.org/?books/plane-trigonometry-with-tables.
