Data/Trig Functions

sine curve regression


make sure your calculator is in radian mode

calculator:

1) stat button-enter data
2) 2nd/stat plot
3) move to dot plot-hit enter
4) set window
5) view graph


sine curve function

after creating the sine curve...

1) stat
2) move to calc-SinReg
3) enter: L1, L2, (commas are important)
4) vars-move to y-vars
5) function
6) enter Y1
7) hit enter

you should see something like:

y=
a=
b=
c=
d=

the data will also be a y= function in Y1

to check other types of curves for fit:

calculator:

1) stat-calc
2) choose a regression-CubReg, QuartReg, etc.-enter
3) enter: L1, L2,
4) vars
5) y-vars-function
6) enter Y2-hit enter
7) view graph
