Sht..stuck on maths homework

-cosec x cot x, if I recall.
Where's your formula sheet? -
derivative of cosec(x) is -cosec(x)cot(x)
uhh.. google is your friend
-
change it to 1/sec x, den dy/dx frm there.
-
Erm... no.Originally posted by TYING:change it to 1/sec x, den dy/dx frm there.
cosec x = 1/sin x.
So you need to apply differentiation to 1/sin x. -
eh!!! paiseh, yar, typo error. Its sin not sec.Originally posted by fudgester:Erm... no.
cosec x = 1/sin x.
So you need to apply differentiation to 1/sin x.

where's your maths book?Originally posted by limywv:Thx thx ppl...but got formula sheets one meh? -
Your textbook dun have meh?Originally posted by limywv:Thx thx ppl...but got formula sheets one meh? -
oh ok..dy/dxOriginally posted by limywv:PLSPLSPLS!!! The previous maths forums closed down liao to make way for football manager -.-
So I need your help now!!!!
What is the derivative of cosec(x)?
PLS! -
how to dy/dx 1/sinx?Originally posted by fudgester:Erm... no.
cosec x = 1/sin x.
So you need to apply differentiation to 1/sin x.
can show ur workings here?
i too long nvr touch A maths le -
wheres ur tys?

Freaking differentiation...
Now pushed to A-level for 1992 babies liao... KNN

1/sin x = (sin x)^-1Originally posted by Classyfied:how to dy/dx 1/sinx?
can show ur workings here?
i too long nvr touch A maths le
d[ (sin x)^-1 ] = -1(sin x)^-2 * cos x = - 1/sin x * 1/sin x * cos x = - cosec x cot x (shown) -
-
i always remember like that one.....
diff tan x=sec^2 x
diff cotan x = -cosec^2 x
so diff bla bla bla x= blah
then diff coblah blah blah= -coblah -

Damn, I guessed they must be pushing those difficult integrations to H1 Maths.
