Let f(z) be complex differentiable everywhere in C. Fix two distinct
complex numbers a and b and a circle C of radius R with |a| < R,|b| < R traversed in the
counter-clockwise direction. Evaluate the integral

- If you are using chatgpt leave it I will downvote .arrow_forwardTemperature measurements are based on the transfer of heat between the sensor of a measuring device (such as an ordinary thermometer or the gasket of a thermocouple) and the medium whose temperature is to be measured. Once the sensor or thermometer is brought into contact with the medium, the sensor quickly receives (or loses, if warmer) heat and reaches thermal equilibrium with the medium. At that point the medium and the sensor are at the same temperature. The time required for thermal equilibrium to be established can vary from a fraction of a second to several minutes. Due to its small size and high conductivity it can be assumed that the sensor is at a uniform temperature at all times, and Newton's cooling law is applicable. Thermocouples are commonly used to measure the temperature of gas streams. The characteristics of the thermocouple junction and the gas stream are such that λ = hA/mc 0.02s-1. Initially, the thermocouple junction is at a temperature Ti and the gas stream at…arrow_forward3) Recall that the power set of a set A is the set of all subsets of A: PA = {S: SC A}.
