The following equation models the number of hours of daylight in New Orleans, Louisiana (30° latitude).  D = 12.5 - 1.9 cos [π (t) /182.6].  In this model, D represents the number of hours of daylight and t represents the day, with t=1 corresponding to January 1 and t=365 corresponding to December 31. Calculate the number of hours of daylight in New Orleans for one of the days LAST week.  Use the day April 20th 2021 to answer this question.  Be sure to explain how you arrived at your answer.

Limits

When it comes to calculus, limits are considered to be a very important topic of discussion. The main importance of limit lies in expressing the value of a function as it gets closer to a certain value. Also, limits can help you to understand other topics, such as continuity and differentiability better. In a broader sense, every calculus notion is a limit. Other branches of calculus have also been derived from limits.
