? The big secret of Taylor formula?

Taylor formula is an important concept in mathematics, which can be used to approximately calculate the values of various functions. This paper will make an in-depth analysis of Taylor formula, so that you can easily master this formula.

Function f(x)=√x

Taylor formula is used to approximate the values of various functions, among which the function f(x)=√x is an important example.

Simple formula

Just remember this simple formula: "Meaning only", that is, √ 2 =1.41421.

Depth analysis

When the function f(x)=√x and x=2, we get f (2) = f (1)+f' (1)+f' (1)/2+... f (n) (65438+. +remainder. In other words, √2 is 1.4 142 1.

Try this formula.

Now try this formula and feel its magic!
