Note, too, that there are three more trigonometric ratios that we will not use much in this class. There is a table to be filled in later in the text. Knowing that they exist and can be calculated is generally enough for a survey course. cosecant B – the reciprocal of sin B. secant B – the reciprocal of cos B. cotangent B – the reciprocal ...

Complete the Unit Circle Worksheet. Complete remaining examples from the lecture notes. Read Sec 2.4. UNIT CIRCLE: A point (x, y) is on the unit circle (circle with radius 1) if . If we draw our common angles on the unit circle we get. If we put these all together and use symmetry, we get the UNIT CIRCLE!

trigonometric ratios or formulas: Part I) Model Problems. Example 1: Consider right DEF pictured at right. We know one acute angle and one side, and our goal is to determine the length of the unknown side x. Step 1: Place your finger on the 38° angle (the acute angle), and then. label the three sides: the hypotenuse. is always the longest side ...

Lesson Worksheet 2. To do this part of the lesson, download this Geometer's Sketchpad file and open it. Recall from the previous section that you found the SIN of an angle to be the ratio of the OPPOSITE side to the HYPOTENUSE. As you may have thought there are ratios that can be formed using the other sides of the triangle.

Math 2 Unit 2 Lesson 2.6B Trigonometric Ratios Aplications. For each problem, draw a picture/diagram showing the right triangle. Then write a trig ratio equation, and solve the equation to answer the problem. * The angle between the HORIZONTAL and a line of sight is called an angle of elevation or an angle of depression (see notes for help). 1.
