How can I solve this e.q

[3d904533cd]

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)

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.

Hello , so I have this question The correct answer is : intervals = a) Dec. intervals: (-1,0)U(1-infinty) inc. (-infinity , -1 ) U ( 0 ,1) b) local max = -1 and 1/4 local min ( 0 , 0 ) the issue is when I solve it the a) = dec (-2 , -1) and inc. (-infinty , 1 ) b) (-1 , -1/4) What...
