For t!=0, f(t) = 1(1/t). Do you know how to derive that?

Do you mean \[\frac{t1}{t}\] or \[t\frac{1}{t}\]?

Oh nvm forget my answer then.

Well you're just doing two separate derivatives then. One for t, and one for 1/t. Can you do these separately?

i think the derivative of t is zero

You don't know what the derivative of t is?

No, 0 is only the derivative of a constant. For example, the derivative of the number 5 is 0. t is a variable that changes, so its derivative can't be 0 (that would imply it's not changing). Yes, 1 is correct for t.

Use to power rule: \[\frac{d}{dx}x^n = n\cdot x^{n1}\] In the first case, n = 1, and in the second case n = 1.

If you know the power rule, you can use it to derive 1/t by first rewriting it as \[t^{1}\]
