In the temperature range between 0 0C and 7000C the resistance R [in ohms] of a certain platinum resistance thermometer is given by R = 10 + 0.04124T à ¢ ˆ ’ 1.779 à ƒ — 10à ¢ ˆ ’5à °  ‘ ‡ 2 where T is the temperature in degrees Celsius. Where in the interval from 0 0C to 7000C is the resistance of the thermometer most sensitive and least sensitive to temperature changes? [Hint: Consider the size of dR/dT in the interval 0 à ¢ ‰ ¤ T à ¢ ‰ ¤ 700
