integrate it from 5 to 10

2. anonymous

$\int\limits_{10}^{5} 7\ln \left| x \right| + 2/t$

3. anonymous

?

4. amistre64

$\int\limits_{5}^{10} \frac{7}{t} + \frac{2}{t^2} dt \rightarrow \rightarrow 7\ln(t) - \frac{2}{t}$

5. amistre64

1/t^2 integrates to (-1/t) :) keep track of those signs

6. anonymous

yeah those signs are gonna kill lol

7. amistre64

15.918 - 10.866 = 5.052 give or take
