Hi, I need help on solving this problem.
I tried to find the antiderivative of this equation first and got:
-ln / 4x^4
I then tried to find the interbals of the width so I did.. 8-2/5 = 6/5 = 1.2
So, thus I added 1.2 to the endpoints and got.. 2, 3.2, 4.4, 5.6, 6.8, 8.
I then plugged it into the equation I solved for to try to find T5, but I keep getting the wrong answer. Is my anti derivative even correct?
