Assertion : f (x) =\[\begin{array}{lll}
(1+x)^{1} & (1+x)^{2} & (1+c)^{3} \\
(1+x)^{3} & (1+x)^{3} & (1+x)^{3} \\
(1+x)^{4} & (1+x)^{4} & (1+x)^{3}
\end{array}\], then coefficient of x in f (x) is zero.
Reason : If F (x) = A0 + A1x + A2x2 + ....... + Anxn, then A1 = F’ (0), when dash denotes the differential coefficient.
Reason : If F (x) = A0 + A1x + A2x2 + ....... + Anxn, then A1 = F’ (0), when dash denotes the differential coefficient.
