Will someone remind me of the chain rule?

Question

Chain rule in Calculus

thanks^_^

Heeyy!! I just ask because I just forgot chain rule!! but I know calc...
^_^
Thanks
^_^
The battle is over... but I must wait 24 hrs to pick the first one, because he reminded me of it!...
Thanks again!!^_^

Answer 1

certainly


dx/dz= dx/du * du/dz and so generallay

dx/dz = dx/du*du/dv........................./dz

Answer 2

there are many chain rule in differential calculus also in Integral calculus. I think upto 25 chain rule included the trigonometric function. However, there is much more in integral calculus i think more than 90 but there is techinique to beused rather than to memorize the formula in integral calculus ex. the trigonometric substitution etc. But in both calculus formula, you must memorize the basic formuola, i think 30 each include hyperbolic functions.

Answer 3

We could, but it would make soooo much more sense to open your calc book, or google "chain rule".

If your smart enough to be in calculus, your smart enough to figure out how to figure something out!!

Answer 4

dy/dx=dy/dt * dt/dx

Eg:
y=(x+2)^2
Let x+2=t
Hence,
y=t^2 t=x+2
dy/dt=2t dt/dx=1
dy/dx=dy/dt * dt/dx
=2(x+2)*1
=2x+4

Answer 5

(d/dx)g(f(x)) = g'(f(x)) * f'(x)
