Cooper elementary school and they’ll explain how to do these differential

equations first of all for us when you change to do y over DX and then you copy

those now you move that to answer and that the outside of e dy over y score

plus 4 equal to now you go this would be turned into tension my 1y and because of

the four did put one or two and over to here and then I got by one so first

things first you copy detention not one and one over two and move that to our

side all right now you move that you keep wrong keep the Y and solve for y

and move that pension to our side so Y over this to equal x squared plus C dot

two but this time there’s a tension here now you move the tool to our site and

try finding the one so why this one I won’t do in a different way so first of

all I want to do it the exact way so instead of going down X you go down one

so I’d be I would be gone some of these two acts left this one is still going

down why you going on X of the X and interests and nothing on so I mean exact now we copy this down so two ants why

not DX go up with the school now you doing something but with this part so I

love these one clothes and school not be y equals y plus X equal Y to X now you

see these two are same right so that means you would copy on and then put

plus y you go see all right now for this

problem you just move around just like that problem so I’d be x dot y school I

mean Y dot d y equal minus X not Y small dot d X so now you do the same you move

that to that side and yeah so why do you why over y school equal minor and not D

X so you see these you can you cut these out now you go on so they’ll be L and y

equal minus X school plus C over 2 so on the y equal the minus X go over to see on our problem sauce and now for this one you do pretty much

the same thing tomorrow you watch for the y’all move the DX last

night so warned it would before I tell you I’m using did on this mana and mana

you could put it to plus so I mean stay why you y equal x over 2
