The power (in microwatts) of a laser is measured as a function of current (in milliamps). Find the linear leastsquares fit for the data points.
The power (in microwatts) of a laser is measured as a function of current (in milliamps). Find the linear leastsquares fit for the data points.
Current (milliamps) | 1.0 | 1.1 | 1.2 | 1.3 | 1.4 | 1.5 |
Laser power (microwatts) | 0.52 | 0.94 | 1.03 | 1.07 | 1.34 | 1.43 |
Note that the coefficients of the linear firstsquare fit for ()=+f(x)=mx+b are determined by the followingequations
X + bn = y
mx^2 + bx=
(Use symbolic notation and fractions where needed. Give the coefficients to two decimalplaces.)
