I calculated the mean which is 78.4 And the Standard deviation is 5.6 I thought the answer would be (90^(-78.4)/78.4!)*e^-90 But looking back having a decimal factorial doesn't make sense I have the numerical answers for c)= 0.019226 and d)=0.022750 but I my solution was wrong. Any help on...

Does the square of the sequence also have a limit of 1. Does the square root also equal 1? I've been trying to find some counterexamples but I think the limit doesn't change under these operations?

Basis would be {x^3+x^2,x^3-x}

and then for the basis i sub these a2 and a1 in forms of a3 into p(x)

ok so i went through a few more examples and ended up with Dim 2 at x=0 i ended up with the equation a0=0 at x=-1 i get a2=a1+a3 so for all values of p(x) in u they can be represented by two parameters (a3-a1)x3+a2x2+a1x

and those numbers can be random? px=3,px=4

x3 x2 x 1 2x3 2x2 2x 1 ?

yea i lost you there. i was reading through the wiki page, do i need a range? or am i making the range lets say i pick the points x=1 and x=2 how would i know the function value from these? am I substituting to p(x)

we can have different basis but dimension will be the same? but yes we can move onto interpolating.

so you can't times x^2 by x only a scalar quantity? or added a certain amount

right so if i wanted to calculate the basis of U which is the vector set and the basis of the subset is { x^3, x^2, x, 1 }. what does that show? The vector space U can have a higher degree than the subset right?

what would other possible basis look like? x^2,x,1?

no?

rightt so the basis is the 1,1,1?

by linear combination are those under +,-,x,÷ and sqrt
