Try this!<BR/><BR/>Write an iteration for generating a parabola using the table mode in a graphing calculator. Without any instructions from the authors. It must have been divine inspiration, because I still puzzle over that bit of nonsense. then imagine having to stare at a college entrance test that has parabolas. Mind boggling.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4983334520933101277.post-57537612856689811702009-02-18T17:43:00.000-08:002009-02-18T17:43:00.000-08:005 x 610 x 620 x 650 x 6100 x 6200 x 6Here is the p...5 x 6<BR/>10 x 6<BR/>20 x 6<BR/>50 x 6<BR/>100 x 6<BR/>200 x 6<BR/><BR/>Here is the problem with a list such as this - there isn't one rule and it is iterative ( must be written recursively). This is a non-standard pattern - meaning there are two rules (not one). Teachers in Singapore do not give problems like this one, because it is confusing and unnecessary.<BR/><BR/>Simplest method using multiplication<BR/><BR/>Start with 5<BR/>Double twice<BR/>Multiply by 2.5<BR/>Repeat step 2<BR/><BR/>5, 10, 20, 50, 100, 200<BR/>30, 60, 120, 300, 600, 1200<BR/><BR/>What most people overlook when they review Core Plus is that not only do students write the equation of lines using a non-standard form: y = a + bx<BR/><BR/>BUT, they also have to describe the rule with an iteration (rule) using tables they create on the graphing calculator. The work is difficult, tedious, and unnecessary. Most adults don't have a clue what the authors are doing. Very little explanation is given - you have to search the calculator resource book, since its not found in either the teacher's edition, nor the student textbook.<BR/><BR/>The authors are complete hacks.Anonymousnoreply@blogger.com
