1. How would you describe the function transformation of f(x)=cos (x) that equals in g(x)= cos (2????x)
2. If a insect is moving up and down a rule that is 50 cm long. The tick marks on the ruler are 1 cm apart. The first tick mark on the ruler is labeled as 0 and the lack tick mark is labeled as 50. Lets call A the location of the "0" tick mark, and B the location of the 50 mark. When we observe (at t=0) the insect is at point A. The insect goes to point B , returns to A and so on. The insect moves at a constant speed of 0.08 m/s. The distance of the insect from A t seconds after we start the observation is described by the function H(t). The function H(t) is periodic, since it repeats identically over time. What is the period and amplitude.
