Calculate the following areas: 1) Limited by the function y = x2 , the x -axis and the points x= -2 and x=2 (10 points). 2) Limited by the function y = 2xe*, the x-axis and the points x=0 and x=3 (20 points). 4x-6 3) Limited by the function y = x2 -3x the x-axis and the points x=4 and x=6. (Tip: you may need a scientific calculator for the last step) (20 points). 4) Limited by the function y = sin 3x , the x-axis and the points x = ( 150) and x = ~ (309). (Tip: you may need a scientific calculator for finding some trigonometric values) (25 points). 5) Limited by the function y = xe*, the x-axis and the points x=1 and x=2 (Tip: you may need a scientific calculator for the last step) (25 points)
