Question

Please help me!!!!
Find the area under the curve y= 3/x on the interval [1,2]

Answer 1

you are being asked to integrate a log function

so its

\[A = \int\limits_{1}^{2} \frac{3}{x} ..dx\]

which can be written as

\[A = 3 \times \int\limits_{1}^{2} \frac{1}{x}..dx\]

hope it helps

Answer 2

A = ∫3/x dx-----------limits 1 to 2

Answer 3

Okay so I just have to integrate that problem and I will have the answer???

Answer 4

yeah

Answer 5

awesome just one minute I am going to integrate it.

Answer 6

so what's ur answer?

Answer 7

Okay I got... \[\int\limits_{1}^{2} 1/x dx = \ln(2) =3\ln(2)\]

Answer 8

I don't know if I did that right.
