Question

Does anyone remember how to use differentials to approximate?

Answer 1

Use differentials to approximate the change in the surface area of a sphere as the radius changes.

Answer 2

at what radius?

Answer 3

related rates?

Answer 4

no.

Answer 5

differentials.

Answer 6

s = 4pir^2
so :
ds = 4pi * 2rdr
ds = 8pirdr

Answer 7

okay thanks

Answer 8

yw

Answer 9

That's all I wanted to know @Coolsector , thanks, no useless info lol

Answer 10

hmm isn't related rates differential @Algebraic! ? http://en.wikipedia.org/wiki/Related_rates

Answer 11

no.

Answer 12

in related rates, you find the RATE of change

Answer 13

with differentials, you find the change itself
