What does this mean...\\n\\n

n_(2)=1.36

\\n1-10 When one knows the true values

x_(1)

and

x_(2)

and has approximations

x_(1)

and

x_(2)

at hand, one can see where errors may arise. By viewing error as something to be added to an approximation to attain a true value, it follows that the error

e_(i)

is related to

x_(i)

and

x_(i)

as

x_(i)=x_(i)+e_(i)

\\n(a) Show that the error in a sum

x_(1)+x_(2)

is\\n

(x_(1)+x_(2))-(x_(1)+x_(2))=e_(1)+e_(2)

\\n(b) Show that the error in a difference

x_(1)-x_(2)

is\\n

(x_(1)-x_(2))-(x_(1)-x_(2))=e_(1)-e_(2)

\\n(c) Show that the error in a product

x_(1)x_(2)

is\\n

x_(1)x_(2)-x_(1)x_(2)~~x_(1)x_(2)((e_(1))/(x_(1))+(e_(2))/(x_(2)))

\\n(d) Show that in a quotient

(x_(1))/(x_(2))

the error is\\n

(x_(1))/(x_(2))-(x_(1))/(x_(2))~~(x_(1))/(x_(2))((e_(1))/(x_(1))-(e_(2))/(x_(2)))

\\n

x_(i)=x_(i)+e_(i),x_(i)=x_(i)-e_(i)

\\na)\\n

x_(1)+Z_(2)=x_(1)-e_(1)+x_(2)-e_(2)\\nxx_(1)+Z_(2)=(x_(1)-x_(2))-(e_(1)+c_(2))\\n(x_(1)-x_(2))-(xx_(1)+x)
