It has been proposed that the ideal temperature for producing a coffee is 90°C. However, this is too hot to enjoy the beverage. After completing the week 5 workshop content, it is up to you to mathematically model how a coffee cup's temperature varies over time 1. Consider a hot cup of coffee. The temperature in the coffee cup will decrease at a rate proportional to the difference in the current tem- perature and the ambient temperature. Based on this...
