On all R, continuous f has ascending coefficients [8, 21, 1, 1], constant term first. Candidate F has ascending rational coefficients [8/1, 8/1, 21/2, 1/3, 1/4]. Does F′=f satisfy the antiderivative premise for the endpoint formula?
G001 — On all R, continuous f has ascending coefficients [8, 21, 1, 1], constant term first. Candidate F has ascending rational coefficients [8/1, 8/1, 21/2, 1/3, 1/4]. Does F′=f satisfy the antiderivative premise for the endpoint formula?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
raw integrand f=[8, 21, 1, 1];ascending powers on all R
After
normalized coefficients=[8/1, 21/1, 1/1, 1/1];declared continuous real polynomial
Conditions: none
The declared integrand is a continuous real polynomial on all R,and endpoints are oriented.Use FTC only under these supplied sufficient hypotheses;finite checks are not a new general formal FTC proof.
