## Question:

The diagram shows the curve with equation y = (x − 2) ln x + 1, x > 0.

a. Complete the table with the values of y corresponding to x = 2 and x = 2.5. Given that b. Use the trapezium rule

i. With values of y at x = 1, 2 and 3 to find an approximate value for I, giving your answer to 4 significant figures.

ii. With values of y at x = 1, 1.5, 2, 2.5 and 3 to find another approximate value for I, giving your answer to 4 significant figures.

c. Use the diagram to explain why an increase in the number of values improves the accuracy of the approximation.

d. Show by integration, that the exact value of ## This problem has been solved!
