How can I solve this e.q

I need when g(t) is increasing and decreasing

also how can I find local points their if it max or min ?

This one is a bit tricky
I can solve a normal e.q by

getting the derivative then getting the stationary points

for ex

but this isn't working what I'm doing wrong ?

Correct method.

However, we cannot tell you WHY it is not working - because you did not show any work!

What did you get for (dg/dt) ?

this is how I tried solving it , like in the video

I tried the power rule derivative method

t^2/(t^2+1)^2 = 2t/4t(t^2+1)

Have you not learned the quotient rule? You can't just take the derivative of the numerator and denominator separately.
