Question

La segona derivada de    P_n(x) = a_0 + a_1 \, (x-a) + a_2 \, (x-a)^2 + \dots + a_n\, (x-a)^n  ,  és

Accepted Answer

\displaystyle \frac{d ^2P_n}{dx^2}=  2a_2 + 3\cdot 2 a_3 \, (x-a) + \dots + n (n-1) a_n \, (x-a) ^{n-2}

Answer

\displaystyle \frac{d ^2P_n}{dx^2}= 2a_2

Answer

\displaystyle \frac{d ^2P_n}{dx^2}= a_1

Answer

\displaystyle \frac{d ^2P_n}{dx^2}= a_1 + 2a_2\, (x-a) + 3a_3 \, (x-a)^2 + \dots + n a_n \, (x-a) ^{n-1}
