 P: 56 how would you solve for the sum of the first 50 terms of 1/(n(n+1)) I know how to do it if there is a common denominator--but i cant seem to find one here, can someone please help(btw, question on a test i just had that i couldt figure out, not hw)
 Sci Advisor HW Helper P: 3,144 Are you familiar with partial fractions? If so then you can do the sum very easily! :)
 Emeritus Sci Advisor PF Gold P: 12,270 Any question related to your coursework should go in homework help, even questions about old exams. Hang on, I'm going to send the thread for a ride over!
