The curve y = sin(x) + cos(x) has two points where the tangent line is horizontal on
the interval 0sxS 27. The y co-ordinates of these points is the positive and negative
square root of a positive integer. What is this integer?
Your Answer:
Can you approximate the height of one of the buildings on your campus, or in your neighborhood? Let us make an approximation based upon the height of a person. In this example, we will calculate the height of a 39-story building.
Acos = xAsin = y
why is it in this problem there is the presence of sin in x and cos in y?
Question: A spelunker is surveying a cave. She follows a passage 180 m straight west, then 210 m in a direction 45°east of south, and then 280 m at 30° east of north. After a fourth displacement, she finds herself back where she started. Use a scale drawing to determine the magnitude and direction of the fourth displacement.

You measure the length and the width of the room as L = 5.8 +- 0.1 m , W = 3.5 +- 0.1 m. What is the absolute error in the area in m2 units?arrow_forwardSolve the same problem as PART 1 but this time analytically. START with the values below. DO NOT USE VALUES FROM PART 1. Suppose you first walk A = 12.0 m in a direction 20.0 degrees west of north and then B=20.0 m in a direction 40.0 degrees south of west. Let the +x-axis coincide with the easterly direction and the +y-axis with the northerly direction. Note: 1. In this problem, DO NOT round values if you need to use them for calculations in subsequent parts. Rounding errors can propagate and can make your final answer lie outside the tolerance limit of 5% set for this problem. 2. While entering answers in the answer box, enter to 3 significant figures. (a) Find the components of A and B along the E and N directions. Enter to 3 significant figures Ax= Ay= Bx= By= m m m m (b) Find the components of resultant R=A+B along the E and N directions.
