The binomial approximation for the square root, + + /, can be applied for the following expression, 1 a + b − 1 a − b {\displaystyle {\frac {1}{\sqrt {a+b}}}-{\frac {1}{\sqrt {a-b}}}} where a {\displaystyle a} and b {\displaystyle b} are real but a ≫ b {\displaystyle a\gg b} .
1 Ιουλ 2017 · Is the binomial expansion a good method to find the approximate value of the square root to second order in $x$? If yes, how should I binomial expand it? $a$ could be a negative number or an imaginary number or a positive number.

In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial. According to the theorem, it is possible to expand the polynomial ( x + y ) n into a sum involving terms of the form ax b y c , where the exponents b and c are nonnegative integers with b + c = n , and the coefficient a ...
How do I use a binomial expansion to approximate a value? Ignoring higher powers of x leads to an approximation; The more terms the closer the approximation is to the true value; For most purposes, squared or cubed terms are accurate enough
The binomial expansion can be used to find accurate approximations of expressions raised to high powers. In Pure Year 1, you learnt how to expand ( + ) where n is a positive integer and , being any constants. We will now learn how to expand a greater range of expressions.
