L(t)= 12+2.8 sin[2pi/365(t-80)]

Use this model to compare how the number of hours of daylight is increasing in Philadelphia on March 21 and May 21. (Assume there are 365 days in a year. Round your answers to four decimal places.

March 21 L'(t)= ?

May 21 L'(t)=?

I found;

L'(t)=2.8cos(2pi/365(t-80))(2pi/365)

- Calc..Help Please -
**MathMate**, Monday, February 20, 2012 at 6:28pmI get the same derivative.

You can post your numerical answer for a check if you wish.
