Statement$-2:$ The number of ways of choosing any $3$ places from $9$ different places is $^9C_3 $.
Its displacement s$(t)$ at time $t$ is given by an equation of the form, $s(t) =$ $\frac{A}{{{c^2}\, - \,\,{k^2}}}$ $(sin\, kt - sin \,ct) $
where $A, c \& k $ are positive constants with $c \ne k,$ then the limiting value of the displacement as $c \to k$ is
