On all R, f has ascending coefficients [1, 1, 3, 2], constant term first and g has ascending coefficients [-1, 1, 1, 1], constant term first. Give the complete normalized ascending integer coefficients of (f+g)′.
G001 — On all R, f has ascending coefficients [1, 1, 3, 2], constant term first and g has ascending coefficients [-1, 1, 1, 1], constant term first. Give the complete normalized ascending integer coefficients of (f+g)′.Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.
Before
f ascending coefficients=[1, 1, 3, 2]
After
real polynomials are differentiable;use coefficient identities
Conditions: none
Coefficient k multiplies x^k;real polynomials differentiate termwise and constants have derivative0.Coefficient identities and a candidate comparison at one point are different claims.

Before
f′ coefficient at degree0 := mul(1, 1)
After
f′ coefficient at degree0 = 1
Conditions: none
Multiply by the original degree and lower it by1;the constant term differentiates to0.

Before
sum derivative coefficient0 := sum(1, 1)
After
sum derivative coefficient0 = 2
Conditions: none
Add derivative coefficients of the same degree,using0 for a missing high-degree term.

Before
[2, 8, 9]
After
complete derivative coefficient identity;zero polynomial=[0]
Conditions: none
The sum rule gives(f+g)′=f′+g′.Removing trailing zeros preserves the polynomial;retain[0] for zero.This is not coefficient inference from a few sample points.
