Deﬁ nitions of Trigonometric Functions of Any Angle Let u be any angle in standard position and let P = (x, y) be a point on the terminal side of u. If r = 2x2 + y2 is the distance from (0, 0) to (x, yas), shown in Figure on the previous page, the six trigonometric functions of U are. Trigonometric Functions of General Angles TRIGONOMETRIC FUNCTIONS OF ANY ANGLE Let θbe any angle in standard position, and let T, Udenote the coordinates of any point, except the origin 0,0, on the terminal side webarchive.icu L T 6 E U 6denotes the distance from 0,0to T, Uthen the six trigonometric functions of àare defined as the ratios: sin à L U N cos à L T N tan à L U T csc à L N U sec à L. Although the trigonometric functions of angles are defined in terms of lengths of the sides of right triangles, they are really functions of the angles only. The numerical values of the trigonometric functions of any angle depend on the size of the angle and not on the length of the sides of the angle. Thus, the sine of a 30° angle is always 1/2 or Inverse Trigonometric Functions When.

The sign will depend on the quadrant. The sign of the cosine depends only on which half. Draw a figure that illustrates the following. What is more, both fall in the same left-or-right half of the x - y plane. Howthen, do we evaluate a function of any angle?Table 3 Trigonometric Functions—Angle in Hundredth of Radian Intervals INDEX Trigonometry. This page intentionally left blank. CHAPTER 1 1 Angles and Applications Introduction Trigonometry is the branch of mathematics concerned with the measurement of the parts, sides, and angles of a triangle. Plane trigonometry, which is the topic of this book, is restricted to triangles lying in. ence angles which reduce the question of nding the trigonometric functions of an angle to that of nding the trigonometric functions of the special an-gles 30 ;45 ;and Let be an angle in standard position as shown in Figure Figure Let P(x;y) be any point on the terminal side. If ris the distance from the origin to the point Pthen by the Pythagorean Theorem, r= p x2 + y2:We de ne. Definitions of Trigonometric Functions of Any Angle Let be any angle in standard position and let be a point on the terminal side of If is the distance from (0,0) to as shown in Figure ,the six trigonometric functions of are defined by the following ratios: y r sin u= x r cos u= y x tan u=, x 0 x y cot u=, y 0. r x sec u=, x 0 r y csc u=, y 0 The ratios in the second column are the. Trigonometric Functions of Any Angle MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. A point on the terminal side of angle θ is given. Find the exact value of the indicated trigonometric function. 1) (6, 8) Find sin θ. A) 3 4 B) 4 5 C) 4 3 D) 3 5 1) 2) (15, 20) Find cos θ. A) 4 3 B) 4 5. Evaluating trigonometric functions Remark. Throughout this document, remember the angle measurement conven-tion, which states that if the measurement of an angle appears without units, then it is assumed to be measured in radians.

Section Trigonometric Functions of any Angle So far we have only really looked at trigonometric functions of acute (less than 90º) angles. We would like to be able to find the trigonometric functions of any angle. To do this follow these steps: 1. 2. 3. 4. Trigonometric Functions of Angles An angle is in standard position if the vertex is at the origin of the two-dimensional plane and its initial side lies along the positive x-axis. Positive angles are generated by counterclockwise rotation. Negative angles are generated by clockwise rotation. An angle in standard position whose terminal side lies on either the x-axis or the y-axis is called a.
