The hot-wire anemometer is an instrument used for measuring velocities or temperatures. If, during its calibration, the output signal E is measured as 0, 1.7, 3.3, and 5.6 V at velocities V of 0, 1, 1.5, and 2 m/s, obtain the gradient dE/dV at V = 0 m/s, using the polynomial representation of the function E(V).
