Question

,

Answer 1

So it's

\[\int\limits_{1}^{2}\frac{ 1 }{ x } dx\]

Answer 2

\[\int\limits_a^b f(x) dx = F(b) - F(a)\]

you are given F(x) and a=1 , b =2

Answer 3

yes

Answer 4

If F(x)=ln|x| + C, and a=1 and b=2, find F(2) and F(1). Subtract them to get the desired definite integral, that is, subtract F(a) from F(b).

Answer 5

I got ln2

Answer 6

Yup, that's correct

Answer 7

thanks guys!
