help please

[sacred oar]

do you know quotient rule

[daring jacinth]

yeah

but i didnt think that would work

ill try it i guess

[daring jacinth]

when i differentiate 1 it just goes to nothing

so how does that work

[sacred oar]

yeah thats fine

[daring jacinth]

oh ok

[daring jacinth]

so i got 2

but its still wrong

[sacred oar]

ok let me try 1s

[daring jacinth]

i ended up with 1 + cosx + sinx / (1 + cosx)^2

[daring jacinth]

cool

wait i might be dumb

hold on

[signal swan]

quotient rule probably works but chain rule would be quicker no?

so f(x) = u^-1 and u(x) = (1 + cosx)

[daring jacinth]

thats what i did and got = -1(1+cosx)^-2

wait idek

[signal swan]

you just got rid of the -sinx

derivative of cosx is -sinx not 1

[sacred oar]

equally fast really

[signal swan]

fair enough

[sacred oar]

since you can see that the top is 1 then it you can just ignore half of the top in a way

since yk itll go to 0

[daring jacinth]

ohhh yeah theres a minus on the top
