# Polynomial IVP Candidates: Initial Data and Finite Residual Grids

This batch has passed Schema, deduplication, source-snapshot, and independent-answer recomputation checks; it is still not marked as human-reviewed.

This question bank has corresponding bilingual step-by-step derivations. Source candidate and English ai_candidate states are retained. AI review, finite computation and Lean formal proof are labelled separately.

## 1. An Initial Value Check Is Not an ODE Check

Use the integer polynomial candidate with ascending-power coefficients=[-10, -3, -2]. Initial data and ODE residuals are separate obligations. Neither a finite grid nor an initial-value match proves existence, uniqueness, a general solution or an identity on an entire interval. x0=-2, required y0=-11. Give (coefficients,x0,y(x0),required y0,match?).

View answer and explanation([-10, -3, -2], -2, -12, -11, No)

Substitute the initial point into the candidate. This checks initial data only and does not check the differential equation. This explicit finite/exact slice is neither a general theorem nor a judgment about a person. The exact result, retaining the requested order, is ([-10, -3, -2], -2, -12, -11, No).

Recompute both derivatives, residual rows and initial values. Finite agreement is not an identity on an entire interval or an existence/uniqueness theorem. This explicit finite/exact slice is neither a general theorem nor a judgment about a person. The exact result, retaining the requested order, is ([8, 3, -2], 1, 0, 0, -3, [-1, 0, 1], [[-1, 3, 7, -4, -1, No], [0, 8, 3, -4, -1, No], [1, 9, -1, -4, -1, No]], -2, -6, 11, -6, 10, Yes, No, No).

## 97. A Second-Order Candidate with Two Initial Data

Use the integer polynomial candidate with ascending-power coefficients=[9, -3, -1]. Initial data and ODE residuals are separate obligations. Neither a finite grid nor an initial-value match proves existence, uniqueness, a general solution or an identity on an entire interval. Relation a*y''+b*y'+c*y=rhs has a=1≠0, b=0, c=0, rhs=-2; input grid=[-1, 0, 1], x0=-1, required y0=12, required y_prime0=-1. Use sorted distinct grid points. Give (coefficients,a,b,c,rhs,grid,every [x,y,y',y'',signed residual,zero?] row,x0,y(x0),y'(x0),required y0,required y_prime0,value match?,derivative match?,all grid and both initial checks?).
