Work through the odd-numbered problems 1-29. Once you have completed the problem set, check your answers.
In problems 1 – 3 , rewrite the limit of each Riemann sum as a definite integral.
In problems 5 – 9, represent the area of each bounded region as a definite integral. (Do not evaluate the integral, just translate the area into an integral.)
5. The region bounded by , the x–axis, the line , and .
7.The region bounded by , the x–axis, the line , and .
9. The shaded region in Fig. 10.
In problems 11 – 15 , represent the area of each bounded region as a definite integral, and use geometry to determine the value of the definite integral.
11. The region bounded by the x–axis, the line , and .
13. The region bounded by , the x–axis, and the line .
15. The shaded region in Fig. 12.
17. Fig. 14 shows the graph of and the areas of several regions.
In problem 19 , your velocity (in feet per minute) along a straight path is shown. (a) Sketch the graph of your location. (b) How many feet did you walk in 8 minutes? (c) Where, relative to your starting location, are you after 8 minutes?
19. Your velocity is shown in Fig. 16.
In problems 21 – 27, the units are given for and . Give the units of .
21. is time in "seconds", and is velocity in "meters per second".
23. is a position in "feet", and is an area in "square feet".
25. is a height in "meters", and is a force in "grams".
27. is a time in "seconds", and is an acceleration in "feet per second per second .
29. For , partition the interval [0,2] into n equally wide subintervals of length . Write the lower sum for this function and partition, and calculate the limit of the lower sum as . (b) Write the upper sum for this function and partition and find the limit of the upper sum as .
