thanks.
I'll try to digest some of this.
The problem for me is the terminology of math.
Financial formulas I can use but I have no clue what the trig terms mean.

Don't worry about it. Aside from a stupid error reading the original
post, I usually do math like you can breathe, but put a dollar sign in
front, and my eyes glaze over.

If you want to *understand* trig, you should first study ratio and
proportion and then similarity, triangles being the simplest example.
Then move into trig ratios, involving sides and angles of a special
triangle, the right triangle.
