Introduction to Trigonometry and study the relationship between side and angle of a triangle. Distinguish various trigonometric ratios and describe and verify sine, cosine, tangent, cosecant, secant, cotangent of an angle. Use given trigonometric ratio(s) and find and verify other trigonometric ratios /angles of the triangle. Introduction
This book covers the major topics within the study of trigonometry, including vectors and their applications. At the University of Minnesota, this material is 75% of the PreCalculus II course, with the remaining 25% of that course covering algebraic topics which are included in a separate text.
1 Introduction. You have probably met the trigonometric ratios cosine, sine, and tangent in a right angled triangle, and have used them to calculate the sides and angles of those triangles. In this booklet we review the definition of these trigonometric ratios and extend the concept of cosine, sine and tangent.
