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.
One of the simplest and most basic formulas in Trigonometry provides the measure of an arc in terms of the radius of the circle, , and the arc’s central angle θ, expressed in radians. The formula is easily derived from the portion of the circumference subtended by θ.
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 among these functions and develops the Pythagorean identities. Lastly, Section 1.6 expands the

Introduction to Trigonometry. OBJECTIVES: 1. Find the ratios, sine, cosine, and tangent given a right triangle and an angle, theta. 2. Solve a right triangle given an angle and at least one side. 3. Know the trig values for the special angles: 30, 45, 60 degrees. 4. Be able to ll in completely a Unit Circle. 5.
13 kwi 2011 · If we let be an angle with initial side along the positive x-axis and terminal side a radius of the circle passing through the point P(x, y), then cos = x and sin = y. The basic trigonometric functions are: sin = y cos = x tan = y/x. csc = 1/y sec = 1/x cot = x/y. can be measured in degrees or radians.
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( ):
