To determine

To write:

A MATLAB code to numerically solve the equation dydx=(1+y2)tanx for 0x0.8 with y(0)=3 using it’s built in function and plot the numerical solution as a solid line and the exact solution as discrete points in one figure. (Exact solution is y=tan[ln[cos(x)]π3] )

Scenario Sales of products by color follow a peculiar, but predictable, pattern that determines how many units will sell in any given year. This pattern is shown below Product Color 1995 1996 1997 Red 28 42 21 1998 23 1999 29 2000 2001 2002 Unit Sales 2003 2004 15 8 4 2 1 2005 2006 discontinued Green 26 39 20 22 28 14 7 4 2 White 43 65 33 36 45 23 12 Brown 58 87 44 48 60 Yellow 37 56 28 31 Black 28 42 21 Orange 19 29 Purple Total 28 42 21 49 68 78 95 123 176 181 164 127 24 179 Questions A) Which color will sell the most units in 2007?
