Please help me write the formula

Hello,
I need to formulate the follow relationship in proper math symbols:

Differential in A (last days value minus today's) has a tendency to reach the Differential in B (today's)

I though this could be expressed with

AΔ -> BΔ

BUt I guess there are more elegant and mathematically correct ways to do this

thank you!

Thank you very much Luc - looks great!)))

Can you also help me understand what the following type of equation means:

f:= a → b

In Mathcad?

Well, you can get it in the following manner:

b is assigned 1 (numerically) then it is undefined for the symbolic processor of Mathcad.

Then a is assigned the value of b.

And finally f is assigned a, with a symbolic evaluation. That reveals that a is actually b, and hence f is effectively assigned b.

QEE

Success!
Luc
