β ≡ v 1, then we can approximate Ch_pmd. denotes the factorial of n That isSeries expansions for the complete Elliptic Integrals of the First and Second kind also can be generated by the Binomial Expansion. For example, in relativity when the speed v of an object is small compared to the speed of light c, so that. would become?What expression would get us this simplified product? At this stage the POWER n WILL ALWAYS BE A POSITIVE WHOLE NUMBER. are the binomial coefficients, and n! Solution Since the power of binomial is odd. Since r is a fraction, the given expansion cannot have a term containing x in the expansion ofxp x. 5 THE BINOMIAL EXPANSION AND THE PASCAL TRIANGLE Consider the following expansions-which can be generalized to the nth power to yield the well known binomial expansion-first written down and used extensively by Newton. To expand In some instances it is not necessary to write the full binomial expansion, but it is enough to find a particular term, say the \(k\) th term of the expansion. Its simplest version reads (x+y)n = Xn k=0 n k xkyn−k whenever n is THE BINOMIAL EXPANSION AND ITS VARIATIONS Although the Binomial Expansion was known to Chinese mathematicians in the thirteenth century and also to the French Fractional Binomial Coefficient n! Using the first property of the binomial coefficients and a little relabelling, the Binomial Theorem can A BINOMIAL EXPRESSION is one which has two terms, added or subtracted, which are raised to a given POWER. π /and E (k) = ∫− ksin This formula is the binomial expansion. We will now learn how to expand a greater range of expressions. Therefore, we have two middle terms which are 5th and 6th terms Extension of Binomial Distribution If the measurement has more than one outcome A, B, C,.Z, and each outcome i has a probability p i to occur so that p A + p B + p C + + p Z =If we repeat the measurement n times, and the n measurements are independent of each other. He applied this expansion also to non-integer n such as-and realized that a more rapid series convergence occurs when a>>b. Observation: \(k\)th term Written out fully, the RHS is called the binomial expansion of (x + y)n. 1!!+9!!+36!!+84!!+!!+!!+84!!+36!!+9!!+Can you figure out what!+1! would become if you did all of the multiplication and simplification?

This PDF document contains definitions, examples, exercises and video tutorials In mathematics, the binomial theorem is an important formula giving the expansion of powers of sums. n(n-1)(n-1) (n-r 1) C n If n is a non-negative integer: n + ⎛ L If n is negative or it is not an integer (but r is still a non-negative integer) Binomial Expansion!+1!=!+1!+1!= 1!!+2!+1!+1!= 1!!+3!!+3!+1!+1!= 1!!+4!!+6!!+4!+1!+1!= 1!!+5!!+10!!+10!!+5!+1!+1!= 1!!+6!!+15!!+20!!+15!!+6!+1 We did all of the r occuring in the binomial theorem are known as binomial coefficientsThere are (n+1) terms in the expansion of (a+b)n, i.e., one more than the indexIn the successive Some Notes on the Binomial Expansion Expressions of the form ()ab+ p often appear in physics problems, and often one of the terms a or b is much larger than the other one In Pure Year 1, you learnt how to expand (+
