In Exercises $1-6,$ sketch the slope fields for the differential equation as follows:

$($a$)$ Pick a few points $(t,y)$ with both $-2t2$ and $-2y2$ and plot the

associated slope marks without the use of technology.

$($b$)$ Use HPGSol ver to check these individual slope marks.

$($c$)$ Make a more detailed drawing of the slope field and then use HPGSolver to con$-$

firm your answer.

For more details about HPGSolver and other programs that are part of the DETools

package, see the description of DETOols inside the front cover of this book.
