To find: the error in the given function.
Answer to Problem 85E
The correct function is,
Explanation of Solution
Given information:
Given function is
Calculation:
Tangent functions formula of trigonometric function is,
We need some values of trigonometric functions,
In this problem,
First, error in denominator.
According to formula, denominator is
Denominator part is only right if
Then,
So the main error is the formula of trigonometric function,
The correct function is,

Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lbarrow_forward
