Notes on Maple 6 and 7 as they affect Calculus: The Maple Way, Second Edition.

p.7: "You should be careful not to include the blank space..."
- this warning doesn't apply any more.

p. 9: "readlib" is no longer needed: if you save "myfunc" into a file
`myfunc.m` in the library directory, the definition of "myfunc" will
automatically be available.  A corollary of this is that you shouldn't
put .m files into the library directory unless you want Maple to always
use the definitions in these files.

p. 10: Maple can now paste in RTF format (which is editable
in Word 2000).

p. 50: fsolve(D(vol)(theta),theta) works.

p. 70: solve(D(theta)(t)=0, t) returns nothing at all.

p. 73: S:= solve(D(f)(x)=0, x); returns not just one RootOf but five
indexed RootOf's.  Use
cp:= fsolve(op(1,S[2]));
and similarly on p. 74.

p. 78: Float(9764639952,232370944) is not used.  There is no error message, 
but eventually you get Float(undefined).

p. 82: "combine" works as stated, but is no longer part of the "student" 
package.  

p. 122: You don't need the first simplify(%);
you do need the second (at the top of p. 123)

p. 148: there is a new bug in contourplot: it doesn't
work with functions that involve a fraction with a 
non-constant denominator (e.g. y/(x^2+1)).  A 
work-around is to use a parametric form of contourplot:
contourplot([x,y,y/(x^2+1)],x=a..b,y=c..d) instead of
contourplot(y/(x^2+1),x=a..b,y=c..d).  A patch is available
in the Maple Advisor Database at
 http://www.math.ubc.ca/~israel/advisor


p. 149.  The two bugs in "densityplot" mentioned at the top of Page 149 have
been fixed.

p. 162.  "readlib" is no longer necessary.

p. 186: Due to a bug,
evalf(Int(Int(x*y^2, x=2-sqrt(1-y^2)..sqrt(4-y^2)), y=-b..b));
does not work.  The error message is misleading.  It works if Digits
is set to 13 or more.  The problem may be in obtaining convergence.

p. 187: Maple now does int(int(ln(cos(x)+y),y=1..2),x=0..1) symbolically,
but due to a bug the answer comes out wrong! 

p. 209: "potential" now works in this example.  So does "simplify(evalm(G-F))".

p. 215: solve(simplify(eq), zc) works.

p. 254: "readlib" is no longer necessary.
