Question

find derivative f = t²-1/t²+t-2 find f'(t) where t is not equal to 1

{WHOEVER ANS. IT FIRST I'LL MARK HIM AS BRAINLIEST}​

Answer 1

Step-by-step explanation:

$\frac{df}{dt} = 2t + \frac{2}{ {t}^{3} } + 1$

As we want $f'(t) /neq 1$. We deliberately set this equal to 1. This reveals $f'(t)=1$ iff $t^4=-1$ which has no real solutions.

We are done.
