5 Trigonometry with right triangles 32 The most beautiful proofs and ideas grew out of material that I learned from him. viii. Lecture 1 The usefulness of mathematics In this lecture we will discuss the aim of an education in mathematics, namely to help develop your thinking abilities. We will also outline several broad approachesTRIGONOMETRIC IDENTITIES Reciprocal identities sinu 1 cscu cosu 1 secu tanu 1 cotu cotu 1 tanu cscu 1 sinu secu 1 cosu Pythagorean Identities sin 2ucos u 1 1tan2 u sec2 u 1cot2 u csc2 u Quotient Identities tanu sinu cosu cotu cosu sinu CoFunction Identities sin trigonometry proofs pdf

When we defined the six trigonometric functions, we proved relationships that are true for all values of u for which the function is defined. There are eight basic trigonometric identities. Proof begins with what is known and proceeds to what is to be proved.

Learning Outcomes At the end of this section you will be able to: Geometry and trigonometry are branches of mathematics where Pythagoras theorem is still widely applied. Trigonometry is a branch of mathematics that allows us to relate the side lengths of triangles to angles.
