Maple Problem Set 

1.  The command solve() looks to solve equations and inequalities, for the variable of interest. On occasion, some solutions may not be discovered. Maple warns the user of this possiblity. The command fsolve() works on equations and it will look for a solution in a particular interval.  It returns a numerical approximation to the solution. 

 

2.  It is appropriate to use [ ] inside the plot function anytime a list needs to be included. A list of expressions: [expression 1, expression 2, etc] or a list of colors, [red, green, blue,black, etc]. 

 

3  Emerald Green is not an officially defined color in Maple.  

4.  The Hex Code is 50C878 and the corresponding RGB values are 80, 200, 120. RGB is shorthand for Red, Green, Blue.  To use these values read: Plot Color Option Help. 

 

#5 

> plot(`+`(sqrt(x), `-`(8)), x = -10 .. 10, y = -10 .. 10, linestyle = longdash, color = ColorTools:-Color([80, 200, 120]));
 

One more thing- this command entry is actually using the Color Command from the ColorTools library. Libraries are introduced in the next chapter.
