The Derivative Song — текст песни (Tom Lehrer)

To "therell be some changes made".



You take a function of x and you call it y,

Take any x-nought that you care to try,

You make a little change and call it delta x,

The corresponding change in y is what you find nex,

And then you take the quotient and now carefully

Send delta x to zero, and I think youll see

That what the limit gives us, if our work all checks,

Is what we call dy/dx,

Its just dy/dx.
