Trigonometry 8th edition mckeague pdf free download
Using Definition II and Figure 8, we would refer to a as the side opposite A, b as the side adjacent to A, and c as the hypotenuse. cosine ii b. cosecant iii c. cotangent i Using the Pythagorean Theorem, first find a: a 2 8 2 17 2 a 2. c 6 c 6 b 5 6 6 5 Now use the Cofunction Theorem to find the three trigonometric functions of B: 5 30 1 6 b sin B cos A cos B sin A tan B cot A 5 6 6 a 6 6.
Using the Pythagorean Theorem, first find c: sin A. Since sec 1it is impossible for sec. b b 2 c c Since b c1 and can be as large as possible. Since secsec can be as large as possible. b b Using the Cofunction Theorem, cos 70 sin Using the Cofunction Theorem, cot 22 tan Using the Cofunction Theorem, csc y sec 90 y, trigonometry 8th edition mckeague pdf free download. Using the Cofunction Theorem, sin 90 y cos y.
x 0 30. First find c using the Pythagorean Theorem: Since CG CD 3using the Pythagorean Theorem: CG 2 CD 2 DG 2 32 32 DG 2 9 9 DG 2 DG 2 18 DG 18 3 2 Now use the Pythagorean Theorem with DGE : DG 2 GE 2 DE 2 3 2. Therefore: GE 3 1 3 DG 3 2 2 cos DE 3 3 3 DE 3 3 3 Let CG CD xusing the Pythagorean Theorem: CG 2 CD 2 DG 2 x 2 sin. Therefore: GE x 1 3 DE 3x 3 Using the distance formula: sin. A coterminal angle to —° is °.
hyp 1 This is impossible trigonometry 8th edition mckeague pdf free download the hypotenuse is the longest side of a right triangle. opp side The opposite and adjacent sides can be any number greater than 0. If we choose a very large tan adj side number for the opposite side and a very small number for the adjacent side, the ratio will approach infinity.
On a calculator, the SIN—1, COS—1, and TAN—1 keys allow us to find an angle given the value of a trigonometric function. Adding the angles: Adding the angles: Adding the angles: Subtracting the angles: 90 Subtracting the angles: Subtracting the angles: Converting to degrees and minutes: Calculating the value: tan Finding the angle : tan 1 6.
csc x sec x cot x error undefined 1 error undefined 3. Finding the angle : tan 1 2. To calculate B, B sin 1 4. Since, for any angle B, sin B 1, it is impossible to find an angle B such that sin B 4.
To calculate cot 0we would find tan 0 0 then find the reciprocal. This results in an error message. Converting to decimal degrees: 1 1 Since cot xtan. Then tan 1. The correct answer is a. Thus the terminal side of lies in quadrant IV. Finding r: 4. Answer to 4 places: 0. Answer: 1. Scientific Calculator: Answer: Scientific Calculator: 0. Answer in decimal degrees is Convert the decimal part to minutes: 0.
Both answers should be 1. Scientific Calculator: 4. Graphing Calculator: 2nd sin 1. The sine of an angle can never be greater than 1. Scientific Calculator: 90 tan Graphing Calculaltor: tan 90 ENTER.
The sin is positive in QI and QII. The cos is negative in QII and QIII. Therefore, must lie in QII. If the sides of a triangle are accurate to three significant digits, then angles should be measured to the nearest tenth of degree, trigonometry 8th edition mckeague pdf free download, or the nearest ten minutes. In general, round answers so that the number of significant digits in your answer matches the number of significant digits in the least significant number given trigonometry 8th edition mckeague pdf free download the problem.
three b. three c. five d. three a. five b. five c. Therefore: 2, trigonometry 8th edition mckeague pdf free download.
Note that A 90 21 Therefore: b a cos 69 sin 69 4. Since the right triangle is a 45°—45°—90° triangle, its height is 2. Re-drawing the figure:. Also note that tan 32 x two expressions equal: x tan 61 14 x tan 32 x tan 61 14 tan 32 x tan 32 x tan 61 x tan 32 14 tan 32 x tan 61 tan 32 14 tan 32 14 tan 32 tan x 7.
Therefore: CAE EAB CAB First find OAD : Now find OAF : 6 12 tan OAD tan OAF 54 54 6 12 OAD tan 1 6. Since From Example 5, we have: h cos 1 h 2 h 2 h The radius is Since x h Therefore: x Substituting : h The radius is ft.
Since x h 30x h. Therefore: x h cos h cos h cos Substituting : h cos ft ft 7 Y1 2 Entering the functions Y1 X 80 70 and Y2 tan 1complete the table: X X 10 5 1 0. Based on these results, it appears the trigonometry 8th edition mckeague pdf free download between the cannon and the horizontal is approximately Let x represent the height of the rider above the center of the wheel which is Since the point of the rider is 50° above the horizontal, we have: h Now find cos note that cos 0 since terminates in quadrant III : 2 cos 1 sin 2.
Multiply both sides by 7. Substitute value for Answer rounded to 4 significant digits Tangent relationship Divide Use calculator to find angle Answer rounded to the nearest tenth of a degree. Cosine relationship Divide First, we find B : Next, we find side c: Sine relationship Multiply both sides by c then divide by. Tangent relationship Change angle to decimal degrees Multiply trigonometry 8th edition mckeague pdf free download sides by 5.
Answer rounded to 4 significant digits Tangent relationship Divide 37 by 87 Use calculator to find angle Answer rounded to nearest degree. Cosine relationship Divide Use calculator to find angle Answer rounded to nearest hundredth of a degree.
Pythagorean Theorem Subtract and simplify Take square root of both sides a must be positive Sine relationship. Multiply both sides by 6 Exact answer Sine relationship Divide Use calculator to find angle Answer rounded to the nearest degree. Next, trigonometry 8th edition mckeague pdf free download, using ABDwe find ABD : h Tangent relationship tan ABD x 19 Substitute known values 21 Divide 19 by 21 0. Multiply both sides by 18 Evaluate right side Substitute value for x Subtract 7.
Using ABCtrigonometry 8th edition mckeague pdf free download, we find side h: Sine relationship Multiply both sides by 28 Answer rounded to 2 significant digits. Solve for x and round to 2 significant digits Since h is in both ABC and BCDwe will solve for h in the two triangles: In BCD.
If an observer trigonometry 8th edition mckeague pdf free download at the vertex of an angle views an object in the direction of the non-horizontal side of the angle, then this side is called the line of sight of the observer. The bearing of a line is always measured as an angle from the north or south rotating toward the east or west. Sketching a figure: 8. Sketching a figure:. trigonometry 8th edition mckeague pdf free download 2 2 2 w Now find angles s and t: cos s s cos 1 Let h represent the height of the hill.
