Hi guys, new to the forums. I've recently purchased a HP 50G for school use. I have a project, there's one part where I have a list of x and y value and I need to fit it into an equation (probably a cosine or sine equation). This calculator is so much different from the TI calculators we use in school, so I have no idea how to do it. I've checked the manual, and it didn't help at all. So can anyone tell me how to fit a list of values into an equation?
