Hello,

I am looking for a function/command in my HP Prime that will expand (1 + X)^4 to X^4 + 4X^3 + 6X^2 + 4X^1 + 1 but I cannot find it.

Does it exist and if so would you please tell me how to get it.

Thanks - Cheers!

Try in CAS mode and in Radians with

taylor((1+x)⁴,x=0)

Very easy is CAS, using the expand() command:

[CAS]
series((1+x)^4) ==> 1+4*x+6*x^2+4*x^3+x^4
