18. Trigonometry: An Introduction

19. Trigonometry (from the Greek Trigona = three angles and metron = measure [1]) is a branch of mathematics which deals with triangles, particularly triangles in a plane where one angle of the triangle is 90 degrees (right angled triangles).Greek[1] mathematics triangles planeangleright angled triangles

20. Trigonometry has important applications in many branches of pure mathematics as well as of applied mathematics and, consequently, much of science.branches pure mathematics applied mathematicsscience

21. The Canadarm robotic manipulator on the International Space Station is operated by controlling the angles of its joints. Calculating the final position of the astronaut at the end of the arm requires repeated use of the trigonometric functions of those angles.Canadarm International Space Station

22. Trigonometry is a division of mathematics that deals with the study of angles. Based on the angles created by triangles and circles, a series of properties were developed that have had an enormous impact on all disciplines of engineering Trig is second only to Calculus for applications in problem solving

23. We will break our study into 2 sections: Triangles and Circles We will consider the ratios created by corresponding sides of similar triangles
