Can so one explain the binomial theorem.
it's similar to pascal's triangle. well the values that is.
What is it used for and how do I make since of it . Thanks
I seen that . Need someone to explain the concept.
: / all I can remember is that you use the ncr key on the calculator. type a regular number press ncr and then type the value of the triangle like 1 or 2.
? WHich part you don't understand?
It's just a formula, plug in the numbers.....
I can't type it correctly.(x+z)^2 = sigma (k n)
n is 2 and k runs from 0 to 2, now just write the sum... eg (x+y)^2 = x^2 +2xy+y^2
