Question 5. Let A be the area enclosed between p (x)= 1 V2-sin x , the x-axis and two vertical lines X= = and 2 3 J X= 1 2 ; let B be the area enclosed between q (x )= , the x -axis and two lines x= = 2+ sin x 2 and X= 3 5 2 Show that A = B (the two enclosed area are equal). // Hints: areas can be expressed as some definite integrals. // Hints: to prove A = B, you can do one of the following: I. Calculate the results of A, B and show they are equal; II. Show A - B = 0; III. Show the expression of A can be transformed into B through algebraically equivalent transforms
