Question

can someone please explain the chain rule in derivatives?

Answer 1

when a function relies on another function we have to account for it

Answer 2

the cahin rule is just saying that the outer function depends on the rate of change of its component function(s)

Answer 3

akshay could u help me

Answer 4

\[f(g(h(x))):f.depends.on.g.which.depends.on.h.which .deoends.on.x\]

Answer 5

f depends on g
which depends on h
which depends on x

Answer 6

\[\frac{df}{dx}=\frac{df}{dg}\frac{dg}{dh}\frac{dh}{dx}\]

Answer 10

this migt help u bro

Answer 11

if your one a plane thats flying thru the air; and you walk from the back to the front; how fast are you going? well, that all depends on how you compute your speed; and the rate of change depends on not only your speed but the planes speed so we account for both.

the chain rule is doing the same thing forrates of change of functions

Answer 12

sqrt(sin^2(x)-3)

1/2sqrt(sin^2(x)-3) depends on: ()^2 - 3

2(sin(x)) depends on: sin(x)

cos(x) depends on x

\[D_x[\sqrt{sin^2(x)-3}\ ]=\frac{1}{2\sqrt{sin^2(x)-3}}*2(sin(x))*cos(x)\]
