On all R, f(x)=(25)x^0, with 0≤n≤5 and x^0=1 even at zero. Give ascending reduced rational coefficients of its zero-constant primitive.
G001 — On all R, f(x)=(25)x^0, with 0≤n≤5 and x^0=1 even at zero. Give ascending reduced rational coefficients of its zero-constant primitive.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
domain=R; coefficient lists are in ascending powers
After
constant term first; rational pairs=[numerator,denominator]
Conditions: none
Fix coefficient order;do not read ascending coefficients as descending or swap numerator and denominator.
Rule: polynomial_representation · Uses: G001
Before
f coefficients ascending=[25]
After
seek F₀ with constant coefficient0 and F₀′=f
Conditions: none
Antiderivatives are not generally unique; this task additionally fixes the constant coefficient at0.
Rule: canonical_primitive_domain · Uses: G001, S001
Before
primitive coefficient at degree1 := div(25, 1)
After
primitive coefficient at degree1 = 25
Conditions: none
Since (x^(k+1))′=(k+1)x^k,divide the coefficient by the positive nonzero integer k+1.
Rule: exact_rational_arithmetic · Uses: G001, S002
Before
differentiate back coefficient0 := mul(25, 1)
After
differentiate back coefficient0 = 25
Conditions: none
Differentiation multiplies back by k+1 and must recover the original coefficient.
Rule: exact_rational_arithmetic · Uses: G001, S003
Before
[0, 25]
After
all derivative coefficients agree with f
Conditions: none
Coefficient agreement proves the polynomial identity on all reals,not merely equality at a few points.
Rule: global_polynomial_identity · Uses: G001, S004
Before
[0, 25]
After
reduced coefficients;integer coefficients retain /1
Conditions: none
Return ascending coefficients,trim redundant leading-in-degree zeros,and retain[0/1] for the zero polynomial.
Rule: coefficient_output_protocol · Uses: G001, S005
