GRAFEQ 2.09
● When Equalities Are Not Equal: Missing Mathematical 
Precision in Teaching, Texts, and Technology; Michael J. Bosse and N. 
R. Nandakumar; Vol. 34, No. 5, November 2003, The College Mathematics 
Journal
"[GRAFEQ] 2.09를 제외하고 모든 그래핑 프로그램은 잘못된 결과의 그래프를 그리는 경우가 있다….. [GRAFEQ] 2.09 는 
다른 모든 프로그램에서 관찰된 잘못된 결과의 그래프를 제대로 보여준다."

● Learning Software Design Competition; 
2001 GRAFEQ was named as an honorable mention - this is the highest rating 
given to any graphing utility this year or last year, when the annual 
competition started.
&nbsp;
GRAFEQ 2.06
● The Common Curriculum Framework for Kindergarten to 
Grade 12 Mathematics; 1999
GRAFEQ has been selected as a "Western Canadian Protocol Key Resource" to 
support The Common Curriculum Framework for Kindergarten to Grade 12 
Mathematics. (GRAFEQ is a depth resource for both Applied and Pure 
Mathematics 10-12.)
&nbsp;
GRAFEQ 2.04
● Scientific Computing World; Ray Girvan; 
November 1998
"Because of its ability to plot highly complex (implicit) equations, GRAFEQ 
will be invaluable to anyone who needs to visualize functions."
● <A hideFocus 
style="selector-dummy: true" href="http://www.zdnet.com/" 
target=new>ZDNet</A>; May 1998
"GRAFEQ is exceptionally easy to use, providing a 'keypad' for entering 
unusual characters." 5 stars (ZDNet's highest rating)
&nbsp;
GRAFEQ 2.03
● The California Instructional Technology 
Clearinghouse; 1997
GRAFEQ has been recommended as "Desirable" by the California instructional 
technology clearinghouse.
&nbsp;
GRAFEQ 2.02 
● Mathematics Teacher; Loring Coes III; November 
1996 
"GRAFEQ is sophisticated but friendly. ... The program ... is a powerful tool 
for investigating topics in advanced algebra, trigonometry and precalculus. 
Teachers and students should find it valuable." 
&nbsp;
GRAFEQ 2.01 
● <A hideFocus 
style="selector-dummy: true" class=sw1 
href="http://www.peda.com/grafeq/reviews/rev941.html" target=new>Recreational 
&amp; Educational Computing</A>; Dr. M. Ecker; October-November 1994 

"Perhaps one of the most immediately noticeable strengths of GRAFEQ is its 
ability to handle equations or other relations besides functions, something 
beyond the pale for graphing calculators and computer algebra systems."
