I assume  you have a TI83 or TI84 calculator?

anonymous · Answer

No I don't, but how can I obtain such a calculator? download online?

hmmm    one sec

anonymous · Answer

it would be very good if there is one calculator like this is available online

jdoe0001 · Answer

well I think this one may work -> http://www.xuru.org/rt/NLR.asp#CopyPaste

jdoe0001 · Answer

but usually a TI83 or later TI models would have sinusoidal regression

anonymous · Answer

on the link you gave me, how would I do the sinusoidal regression?

jdoe0001 · Answer

hmmm   dunno  .... I  tried your set... but dunno what exact pair

that site works well for quadratic regressions and linears... haven't tried them for sine regression

anonymous · Answer

alright, tnx for trying -:(   :)

jdoe0001 · Answer

hehe, it'd be simpler with a TI  =)

anonymous · Answer

yes, probably ... have a good one.

you wouldn't have access to excel or logger pro or matlab or any other graphing software would you? otherwise I'd direct you here: https://math.stackexchange.com/questions/301194/given-a-data-set-how-do-you-do-a-sinusoidal-regression-on-paper-what-are-the-e
