[sdiy] The TL072 , part 2

We are being told today that you don't need calculus for sdiy.  Well, drift 
is a temperature derivative, so it is virtually impossible to understand 
without calculus.  In fact, without a calculus *trick*, it is still very 
difficult to understand, as the equations become very messy and quickly 
expand to many pages.

But people will spout off anyway, won't they?

Hey Ian,

First, many thanks for your web site and designs. A very, very useful site
and I've read through most of it I think. 

With my comments anyway, I counseled Dan, " If you want to do intense new
development and push limits, you will need to bite the bullet and do the
math. If you want to tweak/implement established designs, [you don't have to
know differential calculus]."

I think that's a fair statement. For someone like you, you couldn't do the
innovative things you were describing without the calculus and I wouldn't
ever think of suggesting otherwise. For others who aren't doing cutting edge
new design, just trying to tweak or combine things, more simple math should
be fine.
