Question

The following questions are from Chapter 1. 1. If csc ?=-3 with ? E Q1V find the basic trig functions. (a) cos(0)- (b) sin(0)= (e) tan(e)- 2. If sin ?- what are the 2 angles ? can be in radians. 2 3. Find sin ? and cos ? if the terminal side of ? lies along the line y 3x in Q111. The following questions are from Chapter 2. 4. If the angle of elevation is 45°15', how tall is the post that casts a shadow 10 feet. tow 5. You are using a truck to two a car, the truck exerts a force of 1000 pounds on a rope at an angle of elevation of 10. How much work does your truck do to pull the car 15 feet?

Explanation / Answer

csc theta = -3

hypotenuse = 3

perpendicular = 1

base = sqrt [ 9 - 1 ] = 2 sqrt 2

a) cos theta = 2 sqrt 2 / 3

b) sin theta = - 1/3

c) tan theta = - 1/ 2 sqrt 2 = - sqrt 2 / 4
