Which one?

I have the Algebra one and the Calculus one.

Did he write more?

Are Chris and Dan the same person?

Dan Coffin authored

1) Algebra & Pre-Calculus on the HP-48G/GX

2) Calculus on the HP-48G/GX

under Grapevine Publications Inc.

Three other books for the 48 are

a) Calculus Investigations with the HP-48G/GX

b) Differential Equations using the HP-48G/GX

c) Investigations in Mathematics HP-48G/GX

BEST!

I got one called 'Easy Course in Using and Programming the Hp 48G/Gx'

A second hand book from the library of Dr Ronald Wyllys. It's been a great experience working through the examples.
