Sine function results in singular matrix?

    I am trying to do a sine curve regression on my collected data using my calculator, but when i do it i get an output that says: "Error:Singular matrix". What is happening?

    Can you describe in a little more detail what you are trying to do? By sine curve regression, do you mean linear least squares?
