Find a compact form for generating function of the sequence 1, 8,

The generating function is where

with for .

Recall that for , we have

Taking the derivative gives

Taking the derivative again, we get

Take the derivative one last time to get

So the generating function is

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

sorry man i accidentally pressed yes my bad
