hello, I have one question about data manipulation in mathematica. I've got set of experimental data. Data describe damped oscillation. My question is following: How can I fit these data? I would like to get formula of function which will approximately describe my data and plot this function. my data list: {{0, 54}, {120, 56.5}, {230, 56}, {305, 54}, {340, 53}, {360, 52.7}, {378, 52.5}, {405, 52.5}, {443, 53}, {480, 53.5}, {510, 54}, {540, 54.7}, {570, 54.4}, {602, 56}, {643,56.5}, {660, 56.5}, {685, 56.25}, {706, 56}, {727, 55.25}, {743, 55.5}, {756, 55.25}, {775, 55}, {787, 54.75}, {799, 54.5}, {814, 54.25}, {828, 54}, {845, 53.75}, {858, 53.5}, {877, 53.25}, {894, 53}, {923, 52}, {951, 53}, {983, 53.5}, {1014, 54}} Have anyone an idea? I'm mathematica beginner therefore I'll be grateful for any suggestion. Thanks <<mira
