I know this is a simple derivative, and I'm in calc 3, but I can't seem to figure this one out....

Okay, well that's really small. It's e^t-1/t in case you can't see it.

Have you tried using the quotient rule?

Let

Then,

Let

The rule states that:

For any function composed of a quotient of two other functions, here denoted by , the derivative is:

...So do the substitution.

If you haven't covered the quotient rule, then reply and I'll try another approach (Wink) - March 23rd 2011, 01:40 PMBracketology
Yea, I'm in calc 3....I was just having a brain fart. Thanks. >.<
