Is there a program or any way to do since cosine and tangent regressions on the HP 48?

Can you post here a data and a regression function to see clearly what you needed exactly?!?

Thanks!

Here's the documentation online: http://isa.umh.es/calc/ss49docs/solve49.htm

Scroll down to "Example 3: Nonlinear least-squares" to see an example. In your case, you would simply need to change the data; you will also need to change the formula to something like: 'Y=A*COS(B*T ADD C) ADD D'
