Unformatted text preview: For example, if you see your data and have x = 2 and U= 5, then your values of m1 and m2 will be given by: m1 = x 3 ⋅ U = x 3 ⋅ U = (2) 3 ⋅ 5 = 40 m2 = x = 2 You need to use your own values, of course. This is just an example. 8. So your line will now look like: m1 / (M0 + m2)^3; m1 = 40; m2 = 2 9. Click on Weight Data at the bottom of the same window. 10. Click OK. 11. Open your lab-manual on page 34 and follow the procedure of Performing a Weighted Least-Square Fit starting on step 5. 12. If you get a bad fit or a “singular coefficient matrix” message you need to start over from step 1 and change the m1 and m2 values you used in step 6. Play around with the numbers (multiplying them or dividing them by 10) until you get a nice fit like the one on page 59. 13. Make sure your errors for m1 and m2 are NOT bigger than your base values for m1 and m2....
