In the module, Further Trigonometry, we saw how to use points on the unit circle to extend the definition of the trigonometric ratios to include obtuse angles. 15 tan( )θ= 11 Solution: 1 (15 ) θ tan 53. This online calculator computes the values of elementary trigonometric functions, such as sin, cos, tg, ctg, sec, cosec for an angle, which can be set in degrees, radians, or grads. To evaluate trigonometric functions of other angles, we use a scientific or graphing calculator or computer software. These are versine, haversine, coversine, hacoversine, exsecant, and excosecant. Given the value of one trig ratio, find the other 5 trig ratios. 2: Trigonomic Functions of Acute Angles The six trigonometric functions What you'll Learn About Right Triangle Trigonometry/ Two Famous Triangles Evaluating Trig Functions with a calculator/Applications of right triangle trig. OBJECTIVE 3: Finding the Values of the Trigonometric Functions of Quadrantal Angles. 4 in your book. There are six basic trigonometric functions and they are sine, cosine, tangent, secant, cosecant and cotangent. 74 The AP CALCULUS PROBLEM BOOK 3.
