Definite Integration

Question:

Evaluate the integral \(\int_3^7(1/(x-2)\,dx=?\)

Options:

 log(5)

 log(7)

 log(2)

0

Correct Answer:

 log(5)

Explanation:

We have integral  \(\int_3^7(1/(x-2)\,dx=?\)

\(\int_3^7(1/(x-2)\,dx= {log(x-2)})\) for x=3 to x= 7

                            =-{log(7-2)- log(3-2)}

                            = log(5)- log(1)

                            =  log(5)- 0

                            = log(5)
