网页In this booklet we review the definition of these trigonometric ratios and extend the concept of cosine, sine and tangent. We define the cosine, sine and tangent as functions of all real numbers. These trigonometric functions are extremely important in science, engineering and mathematics, and some familiarity with them will be assumed in most
网页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.
网页Section 1.4 completes the definition of trigonometric functions, using the Unit Circle, by introducing tangent, cosecant, secant, and cotangent functions. Section 1.5 explores connections

网页Trigonometric functions are special kinds of functions that express relationships between the angles of right triangles and their sides. For example, consider the right triangle (with hypotenuse 1) drawn below. The relationship between the side length y and the angle μ is given by the function y = sin(μ). μ.
