EXAMPLE 10

Finding the Sine Function of Best Fit

Use a graphing utility to find the sine function of best fit for the

data in Table 11 on page 429.

SOLUTION

To draw the scatter diagram follow the same steps as those

presented in Section 1.7. To find the sinusoidal function of best

fit, follow the same procedure as that presented in Section 5.8 (this

section shows how to store the function of best fit in

you should select C: SinReg under the STAT, CALC menu:
