I have data points for a damped vibration graph. How can I get a function? I need a function that combines a sine graph with a decreasing exponential function.

Define parameters:


C = 1

w = 1

f = 1

k = 1


Create the model function, e.g.


model(x) = e^(-k x) C sin(w x + f)


Then issue the command Fit[list1, model]
