The power generated by a windmill varies with the wind speed. In an experiment, the following five nents were oltainedElectrie Power W) 320 Electric Power (W) 320 490 540500 480 Case 1 Determine the fourth-order polymomial in the Lagrange form that passes through the points. Use Case 2 Use linear splines interpolation with the data in the table to calculate the power at a wind speed Case 3 Compare both results (in %). the polynomial to calculate the power at a wind speed of 26 mph. of 26 mph
