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.
This text covers the content of a standard trigonometry course, beginning with a review of facts from geometry.
This text covers circular and right-triangle trigonometry, analytic trigonometry (identities and trigonometric equations), and applications, and spends just enough time on vectors, complex numbers, and polar coordinates to neatly round out the semester.
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.
Basics of Trigonometry. One way to think about the trigonometric functions is in terms of the unit circle (that is, the circle centred at the origin, of radius 1). If (x; y) is a point on the unit circle corresponding to an angle , then. = cos( ) and. = sin( ):
