Does anyone remember how to use differentials to approximate?

OpenStudy (bahrom7893):

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

OpenStudy (anonymous):

at what radius?

OpenStudy (lgbasallote):

related rates?

OpenStudy (anonymous):

no.

OpenStudy (anonymous):

differentials.

OpenStudy (anonymous):

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

OpenStudy (bahrom7893):

okay thanks

OpenStudy (anonymous):

yw

OpenStudy (bahrom7893):

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

OpenStudy (lgbasallote):

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

OpenStudy (anonymous):

no.

OpenStudy (bahrom7893):

in related rates, you find the RATE of change

OpenStudy (bahrom7893):

with differentials, you find the change itself
