Transcript

00:00

Thank you We sneak here's your shmoop du jour brought

00:05

to you by grafs gone wild they're clearly the result

00:09

of bad parents which of the following is the direction

00:13

field for the differential equation Y prime equals x times

00:17

sign of why And hear the potential answers All right

00:23

well whoa these air some trippy grass we really need

00:26

to stop eating so many sugary foods just before that

00:29

time Okay so the key to finding the right direction

00:32

field for a product of functions is to think about

00:35

the direction field for each part of the product And

00:38

then imagine what happens when we multiply You know that

00:42

sign is a periodic function which means it'll repeat interval

00:47

after interval after interval after interval like that we're given

00:51

the sign of why so we know that the direction

00:53

field will repeat in the right direction looking at the

00:57

given direction fields the only one that is periodic in

01:01

the wider action is answer choice See the other direction

01:04

Fields are only periodic in the ex direction so answer

01:08

sees alfio excuse us We're going to go during some

01:11

warm milk and go straight to bed hopefully will dream 00:01:14.539 --> [endTime] Something single line brass
