If we want to raise a binomial expression to a power higher than 2 (for example if we want to find (x+1)7) it is very cumbersome to do this by repeatedly multiplying x + 1 by itself. In this unit you will learn how a triangular pattern of numbers, known as Pascal's triangle, ...

In Chapter 1 we introduced the numbers ( kn ) and called them binomial coefficients . It is time to explain this strange name: it comes from a very important formula in algebra involving them, which we discuss next.L.LovászJ.Pelikán...
This is called the law of Pascal triangle and it provides a rapid way of computing binomial coefficients successively. 上图由二项式系数构成的三角形叫作帕斯卡三角形Pascal's Triangle,也叫杨辉三角形,它是快速计算二项式系数的工具。注意三角形的位置和 Cnk 的对应关系,行和列都是从0开始的。由二项式的系数...
Depending on the values ofand, the number in Pascal's triangle may not be exactly equal to the coefficient in the final answer. So, this is how to identify the coefficient of theth term in a binomial expansion in the form(a+b)xusing Pascal's triangle. ...
Binomial Theorem or Pascal Triangle: The Binomial expansion for any positive integral n is, (a+b)n=nC0an+nC1an−1b+nC2an−2b2+...+nCnbn, and the value of nCr is n!r!(n−r)!. The coefficients of the Binomial expansion are arranged in an array. This i...

How do you use the binomial theorem on large binomials? What does k stand for in the binomial theorem? What is binomial theorem used for? What is binomial theorem? How to expand using binomial theorem How to make a model of Pascal triangle ...
The complete order of polynomial basis functions in two-dimensional space up to the nth order can be given by using the so-called Pascal triangle, shown in Figure 3.2. The number of terms used in p depends upon the number of nodes the 2D element has. We usually try to use terms of ...
