Abstract, Experiment, and Observation Abstract: The objective of this lab was to review basic trigonometric functions. In the lab basic trigonometry was used to calculate the height of a building using a weight hanging from a protractor as well as calculating sides and angles of triangles made using string and tape. The lab revealed the accuracy of the trigonometric functions by comparing the actual with the calculated values. Even though the calculations weren’t one hundred percent accurate, they were close enough to be considered correct and useful Experiment: Lab Setup: Materials: Masking/Scotch tape Protractor Straw Tape measure String Weight Computer and spreadsheet program

Procedures 1. Create a triangle by taping a string against a wall and taping the bottom of the string to the floor or a table set against the wall. Make sure that the wall is perpendicular to the floor or table by measuring angle C, which should be 90 degrees 2. Measure sides a, b, and c of the triangle with a tape measure and record these values in centimeters (cm) on your data sheet. 3. Measure angles A and B of the triangle with a protractor and record on your data sheet. 4. Using the values for the sides of the triangle that you measured in step 2, compute angles A and B by using the different trigonometric functions. 5. Calculate the average value of the computed angle A by adding the three computed values of A and dividing by 3. Record this value on your data sheet. 6. Calculate the average value of the computed angle B by adding the three computed values of B and dividing by 3. Record this value on your data sheet. 7. Compare the values of the measured angles with the average computed values and determine their difference. 8. Create a new triangle by taping the bottom of the string to a different position on the floor or table, as in Procedure 1. 9. Measure the hypotenuse c of the triangle with a tape measure and record this value in centimeters (cm) on your data sheet. 10. Measure angle B with a protractor and record on your data sheet.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
