Electrical Resistance The resistance of a certain type of resistor is where is measured
Chapter 3, Problem 87(choose chapter or problem)
Electrical Resistance The resistance R of a certain type of resistor is \(R=\sqrt{0.001 T^{4}-4 T+100}\), where R is measured in ohms and the temperature T is measured in degrees Celsius.
(a) Use a computer algebra system to find dR/dT and the critical number of the function. Determine the minimum resistance for this type of resistor.
(b) Use a graphing utility to graph the function R and use the graph to approximate the minimum resistance for this type of resistor.
