Winter (/ˈwɪntər/) is the coldest season of the year in temperate climates‚ between autumn and spring. It is caused by the axis of the Earth in the respective hemisphere being oriented away from the Sun. Different cultures define different dates as the start of winter‚ and some use a definition based on weather‚ but when it is winter in the Northern Hemisphere it is summer in the Southern Hemisphere‚ and vice versa. In many regions‚ winter is associated with snow and freezing temperatures. At the

Choose one of the forecasting methods and explain the rationale behind using it in real life. I would choose to use the exponential smoothing forecast method. Exponential smoothing method is an average method that reacts more strongly to recent changes in demand than to more distant past data. Using this data will show how the forecast will react more strongly to immediate changes in the data. This is good to examine when dealing with seasonal patterns and trends that may be taking place. I would

high temperature of 1000K. However‚ it takes time to take the ball from the furnace to the quenching bath and its temperature falls. If the temperature of the furnace is 1200K and it takes 10 seconds to take the ball to the quenching bath‚ is less time needed or more time needed to reach temperature of 1000K I assumed assumed that the ball bearing is cooled by radiation and convection to its surroundings. I decided to use 4th order Runge Kutta method to solve the problem. Objective To solve
