| 00:0-1 | here . Why varies inversely with X . Remember that | |
| 00:05 | when we have two sets of inversely related coordinates X | |
| 00:10 | one and Y one and X two and Y two | |
| 00:13 | . We can use the product rule Excellent times Y | |
| 00:17 | one equals X two times Y . To to find | |
| 00:20 | a missing value . Here , we know that . | |
| 00:24 | Why was 8.2 ? When x equals 0.2 . So | |
| 00:29 | one set of coordinates will be 0.2 , oh And | |
| 00:35 | 8.2 . We want to know the value of Y | |
| 00:40 | when X is equal to 0.4 . So are other | |
| 00:45 | coordinates will be 0.4 . And why simplifying 0.2 times | |
| 00:54 | 8.2 is equal to 1.64 . Oh 0.4 times Y | |
| 01:03 | is equal to zero point for Why ? Now we | |
| 01:08 | saw for what ? By simply dividing both sides of | |
| 01:11 | the equation by 0.4 . Yeah , 1.64 divided by | |
| 01:23 | 0.4 is equal to 4.1 , 0.4 and 0.4 cancel | |
| 01:30 | each other out , So 4.1 is equal to Y | |
| 01:35 | , So when X is equal to 0.4 , why | |
| 01:39 | is equal to 4.1 ? Yeah . |
