Which is the correct equation for hermit interpolation?
a) 𝓅(𝓊) = 𝒫k(2𝓊3 − 3𝓊2 +1) + 𝒫k+1 (−2𝓊2 + 3𝓊) + 𝒹𝓅k (𝓊3 −2𝓊2 + 𝓊) + 𝒹𝒫k+1 (𝓊3 −𝓊2)
b) 𝓅(𝓊) = 𝒫k(2𝓊3 − 3𝓊2 +1) + 𝒫k+1 (−2𝓊2 + 3𝓊) + 𝒹𝓅k (𝓊2 −2𝓊 + 𝓊) + 𝒹𝒫k+1 (𝓊3 −𝓊2)
c) 𝓅(𝓊) = 𝒫k(2𝓊3 − 3𝓊2 +1) + 𝒫k+1 (−2𝓊3 + 3𝓊2) + 𝒹��k (𝓊3 −2𝓊2 + 𝓊) + 𝒹𝒫k+1 (𝓊3 −𝓊2)
d) 𝓅(𝓊) = 𝒫k(2𝓊3 − 3𝓊2 +1) + 𝒫k+1 (−2𝓊2 + 3𝓊) + 𝒹𝓅k (𝓊2 −2𝓊 + 𝓊) + 𝒹𝒫k+1 (𝓊2 −𝓊)
