HeidiD Posted May 6, 2009 Share Posted May 6, 2009 I've forgotten everything learned in college. :tongue_smilie: From Life of Fred, page 38 "using the delta process, find limit of ΔY / ΔT as ΔT approaches 0 for y=1/ T ^2" My question is, how does one square or multiply a delta by another delta? eg. (T+ΔT) X (T+ΔT) Quote Link to comment Share on other sites More sharing options...
Jane in NC Posted May 6, 2009 Share Posted May 6, 2009 Delta T is an increment. Hence (T + DT)^2 = T^2 + 2TDT + (DT)^2. (Not sure how you entered the nifty deltas...) Do not be tempted to separate the Delta from the T --treat it as an entity. Have you found a common denominator for the limit problem that is posed? Sorry, I don't own LoF but I hope this helps.

Jane Thanks so much, Jane. I really appreciate it! The nifty deltas - copied and pasted. :) Quote Link to comment Share on other sites More sharing options...
