Question

I dont understand this at all.
Estimate deltaf using the Linear Approximation and use a calculator to compute both the error and the percentage error.
f(x)=sqrt(6+x) a=3 deltax=−0.1

deltaf is estimate to be:
With these calculations, we have determined that the square root of: is approximately:
The error in Linear Approximation is:

Answer 1

Of course, when you try to fit a curve and straight line, there is always some space ... which gives different value of Y in f(x) curve and linear approximation.

more the value of delax more the error is.

Answer 2

this crap has me so lost.

Answer 3

first of all do you know that linear approximation is?

Answer 4

... of course there will be error, and besides, you are using general term, 'a', so you get the general equation of error in 'a' which will make you more confusing, why not try simple problems first
