In the complex plane, let C be the circle |z| = 2 with positive (counterclockwise) orientation. Then a. 0 b. 2(pi)(i) c. (pi)(i)/2 d. (pi)(i)/8 e. (pi)(i)/16 Answer: D I don't know how to solve it, really no idea :(. May you help me????

yeah, bluefly and dragonfinity already explained it clearly. for the second intersection on the right of y-axis, it is between 74 and 75. Isn't it? :) Using continuous function and f(a)*f(b) cheers

dragonfinity, your answer was great. But the given question was wrong. It should be p'(-3)

hi, I would like to have that book also. poor me, i dont have credit card for purchase. Is there any ebook version for that book? :))

hi everyone, Thanks vvaann so much for sending me the materials. I got it this morning and it was a big shock for me. Like you said before, it was a stupid waste. Only 20 pages for formulas, and no exercises at all !!!. I also say: don't read it. Thanks to Dragonfinity for advising me the book. But I have no time from now for purchasing it. It's too late. Again, "Princeton review: cracking the gre math test" has ebook version???, that's is the only way I can do. Take care,
