ANALYSIS OF DATA Analytical Method**Show sample calculation for Analytical Method: **a) Ax = A cos , Ay = A sin  (or similarly use Bx, By, or Cx, Cy)b) Rx = Ax + Bx + Cx, Ry = Ay + By + Cyc) R = (Rx2 + Ry2)1/2 d)  = arctan(Ry / Rx) + 180Graphs (Polygon Method) & Sample Calculations1.

Calculation of % Differences between Analytical and: a) Graphical b) Direct Table of Results (Analysis Sheet on Excel File) All major results are summarized here3CONCLUSIONError Analysis1. Discuss the range of mass and angle variation on: a) force table and b) graphical method. These ranges should have been used to deduce the uncertainty in the force table (accidental uncertainty) and graphical (instrumental uncertainty) methods. 2. Suggest changes in the experimental design and/or procedure which would make the individualreadings & hence final results more accurate.Discussion1. Were the objectives of the lab met? 2. Discuss whether experimental data (force table) were verified by analytical & graphical methods. In other words, did they agree within their respective uncertainties?3. Which of three methods was most accurate?
