Medium shot

“At this point I just need to get a bit technical and explain some proper terminology since ‘infinity’ is not really a number! I will do this using a simple fraction where I have a variable in the denominator”

|
Graphic
|
Graphic #9 indicating that numbers can get close to zero from both positive and negative directions
|
Voice over
“Notice in this table as the value of the denominator gets closer to zero we can approach zero using both positive and negative decimals. As the value of the denominator approaches 0 from the positive direction our expression gets infinitely large and POSITIVE.
As the value of the denominator approaches 0 from the negative direction our expression gets infinitely large and NEGATIVE.
In this case we say that zero is a non-permissible value of the denominator because it makes the expression UNDEFINED. We use the word UNDEFINED versus INFINITY in this case because as the values get infinitely large or infinitely negative as the values of x approach zero from both sides of zero.

46. Explanation of Non-permissible values

|
Classroom
have 1/x written on white/chalk board
|
Medium shot
words “non-permissible values (NPV)” on lower end of screen (as a subtitle)
“undefined”
|
“These values that make the denominator zero and therefore the expression undefined are called “non-permissible values of the denominator” simply because they are not permitted to be there! we say that they make the expression undefined!
So, fpr the expression 1/x zero was a non-permissible value of the denominator because it made the expression undefined.

“For question #1 I know that if I plug in 0 right away for x that will make the expression undefined so the NPV is 0”

5:37 - 5: 44
|

|
extreme close up of student #2’s handwritten work

voice over
“for question #2 I know that if I plug in 1 for x that will make the denominator 0 making the expression undefined so the NPV is +1”

5:45 - 5:53
|
classroom
|
extreme close up of student #3’s handwritten work
|
voice over
“for question #3 I know if I plug in -2 for x that will make the denominator 0 making the expression undefined... so the NPV is -2”

55. Student #4 solution
|
5:54 - 6:10
|
classroom
|
extreme close up of student #4’s handwritten work
|
voice over
“for question #4 I think using factors would be easier for this! I factored the denominator which allows me to recognize my non-permissible values easier. know that if I plug in 3 for x for one factor and -5 in for the other factor these values will make the denominator 0 making the expression undefined. Therefore the NPVs are +3 and -5”.

Mr. H explaining “To summarize, non-permissible values of denominator pop up everywhere in mathematics, particularly in calculus. Having an understanding of why you cannot divide by zero and being able to identify non-permissible values of the denominator will help you understand the concept of limits and allow you to draw complicated graphs later on in future math courses!”
