2 2

3 Caution The 1 in f 1 is not an exponent. 3

4 Inverse Sine Function 4

5 Inverse Cosine Function 5

6 Inverse Tangent Function 6

7 Domain and Range of Inverse Functions 7

8 How to Find Function Values Using Definitions of the Trigonometric Functions? Evaluate a) Let The inverse tangent function yields values only in quadrants I and IV, since 3/2 is positive, θ is in quadrant I. 8

9 How to Find Function Values Using Definitions of the Trigonometric Functions? (Cont.) Sketch and label the triangle. The hypotenuse is 9

10 FINDING FUNCTION VALUES USING DEFINITIONS OF THE TRIGONOMETRIC FUNCTIONS (continued) Since arccos is defined only in quadrants I and II, and is negative, θ is in quadrant II. Sketch A in quadrant II, and label the triangle. 10

11 11

12 Another Example Evaluate the expression without using a calculator. Let arcsin (2/5) = B Since arcsin (2/5) = B, sin B = 2/5. Sketch a triangle in quadrant I, find the length of the third side, then find tan(b). 12

13 Another Example (Cont.) 13

14 FINDING FUNCTION VALUES USING IDENTITIES Evaluate the expression without a calculator. Use the cosine sum identity: 14

15 Sketch both A and B in quadrant I. Use the Pythagorean theorem to find the missing side. 15

16 16

17 How to Solve a Trigonometric Equation? Step 1: Decide whether the equation is linear or quadratic in form, so you can determine the solution method. Step 2: If only one trigonometric function is present, first solve the equation for that function. Step 3: If more than one trigonometric function is present, rearrange the equation so that one side equals 0. Then try to factor and set each factor equal to 0 to solve. 17

18 How to Solve a Trigonometric Equation? (Cont.) Step 4: If the equation is quadratic in form, but not factorable, use the quadratic formula. Check that solutions are in the desired interval. Step 5: Try using identities to change the form of the equation. If may be helpful to square both sides of the equation first. If this is done, check for extraneous solutions. 18

19 Example of Solving Trigonometric Equation Using the Linear Method Solve 2 cos 2 x - 1 = 0 Solution: First, solve for cos x on the unit circle. 19

20 Example of Solving Trigonometric Equation by Factoring Solve 2 cos x + sec x = 0 Solution: Since neither factor of the equation can equal zero, the equation has no solution. 20

21 Example of Solving Trigonometric Equation by Squaring Solve cos x + 1 = sin x [0, 2 π] Check the solutions in the original equation. The only solutions are π/2 and π. 21

22 Example of Solving a Trigonometric Equation Using a Half-Angle Identity a) over the interval [0, 2 π), and b) give all solutions Solution: Write the interval as the inequality 22

23 Example of Solving a Trigonometric Equation Using a Half-Angle Identity (Cont.) The corresponding interval for x/2 is Solve Sine values that corresponds to 1/2 are 23

24 Example of Solving a Trigonometric Equation Using a Half-Angle Identity (Cont.) b) Sine function with a period of 4, all solutions are given by the expressions where n is any integer. 24

25 Example of Solving a Trigonometric Equation Using a Double-Angle Identity Solve cos (2x) = cos (x) over the interval [0, 2 ). First, change cos (2x) to a trigonometric function of x. Use the identity 25

26 Example of Solving a Trigonometric Equation Using a Double-Angle Identity (Cont.) Over the interval 26

27 Example of Using the Multiple-Angle Identity Solve over the interval [0, 360 ). 27

28 Example of Using the Multiple-Angle Identity(Cont.) List all solutions in the interval. The final two solutions were found by adding 360 to 60 and 120, respectively, giving the solution set 28

29 Another Example of Using the Multiple-Angle Identity Solve tan 3x + sec 3x = 2 over the interval [0, 2 π). Tangent and secant are related so use the identity 29

30 Another Example of Using the Multiple-Angle Identity(Cont.) 30

31 How to Solve an Equation Involving an Inverse Trigonometric Function? Example: Solve 2 arcsin Solution: First solve for arcsin x, and then for x. The solution set is {1}. 31

32 Example: Solve Another Example Solution: Let Then sin and for u in quadrant I, the equation becomes 32

33 Example of Simplifying Expression Using the Half-Angle Identities Sketch a triangle and label it using the facts that u is in quadrant I and Since x = cos u, x= = 33
