Old exams
Final Exam: Monday, Dec. 15, 1:30-3:30, Room 0101
Answers to Fall 2002 Math 141 Final (not the 141H final):
1.(a) 9/2 (l'Hopital) (b) (pi/4)-(1/2) (by parts)
2. (a) (5 ln sin x + 5x cot x)(sin x)^(5x) (take ln y, then differentiate to get y'/y = ...)
(b) y=2/(1-ln(1+x^2))
3. (-1/9)sqrt(x^2 + 9)/x
4. -1/(x+1) + 1/(x-1) + (-1)/(x-1)^2 (note that x^2-1 = (x+1)(x-1))
5. a real number, namely pi/4 (complete the square)
6. Ignore
7. Done in class
8. (a) integral from -1 to 1 of (pi)(4-x^2) dx (disc method)
(b) 3/5 (it's a geometric series with ratio -1/4)
9. -65/144 (3 terms)
10. R=2
11. (a) converges (take absolute values, then compare with sum 1/n^2) (b) diverges (integral test)
12. sum for n=0 to infinity of (-1)^n x^(6n+1) / ((6n+1)((2n)!))
(note that f'(x) = cos(x^3),
which can be expanded into a Taylor series. Then integrate)
