I posted this on the level I forum but thought ya’ll may find it usefull if you forgot how to do SYD & DD deprc If your having a hard time memorizing the different depr methods and have TI BAII PLUS. All the depr methods are built into the calculator. CHech it out hit 2nd DEPR (4). There yoiu can pick your depr method. Read the manual to learn how to do each method… double decline, SYD, SL (if you need help with SL god help you). Your TI BAII plus will also do breakeven and nom vs EFF. Enjoy
