Through the binomial expansion of $(1 - 2x)^\frac{1}{2}$, I am required to find an approximation of $\sqrt2$. Binomial expansion $ (1 + x)^n = 1 + \frac{n}{1}x + \frac{n(n-1)}{1*2}x^2 + .....

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} .
Free Binomial Expansion Calculator - Expand binomials using the binomial expansion method step-by-step.
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 ...
1 lip 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.
6 mar 2023 · You can check that that is an approximation of root 2 by calculating its square. If you want you know why this works, you could start with https://en.wikipedia.org/wiki/Binomial_approximation, particularly the generalisation near the end.
13 wrz 2023 · 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
