Document Summary

Math 1300 lecture 3 notes mathematical models: a catalog of essential functions. It is important to realize the limitations of the model. In the end, mother nature has the final say: there are many different types of functions that can be used to model relationships observed in the real world. If we use a graphing calculator, we enter the data into the data editor and choose the linear regression command. (with maple we use the fit [leastsquare] command in the stats package; with. Mathematica we use the fit command. : the machine gives the slope and y-intercept of the regression line as m 1. 71262 b . 23054. 14: so our least squares model for the co2 level is 2 c 1. 71262t 2 3054. 14. Consequently, we are far less certain about the accuracy of our prediction: using equation 2, we see that the co2 level exceeds 420 ppm when 1. 71262t 2. 420 solving this inequality, we get t .
