Today Joshua and I worked on Free Response Questions in a Mock Exam. They were very challenging and were a good review of many concepts. The first problem gave us information on a piston that oscillated up and down. The given information included its maximum and minimum heights and how high the piston was above ground level. We were first asked to find what the coordinates of various points on the graph could be. Then we were asked to write a sinusoidal function that could model various points. Then we were asked to find the period, amplitude and phase shift. Joshua and I worked together to brainstorm possibilities. We checked our solutions to see we got it right! Then we tried another FRQ involving logarithms and exponential functions. Josh took the lead on this problem. He ran into some trouble remembering properties of logs, so it was a good review for him. We did not finish this question (it has multiple parts), so Josh will finish it for HW.
