Part 1 - Application A mass oscillating up and down on the bottom of a spring (assuming perfect elasticity and no friction or air resistance) can be modeled as harmonic motion. If the weight is displaced a maximum of 6 cm, nd the modeling equation if it takes 4 seconds to complete one cycle. Be to show, illustrate and explain your work. Part 2 - Find the error(s) and solve the problem correctly. Be sure to explain and show your work. Where did the "wrong answer" come from? Sin 52 Answer: sin 52 = .9866 Part 3 - Discussion Question Name 4 other angles whose cosine is the same as cos %. Explain using mathematical language how you know this is true. (calculations only using a calculator is not considered mathematical language). Is this statement true or false? Explain your answer. All angles that have the same cosine will have the same sine
