Find the limits
Lim(sin kt/t) t approaches 0 and (K is constant)
How do you start this and go about it stepwise?
Does knowing (K constant) help me to solve this?
You can do this in one step.
As t -> 0, sinkt -> kt, so
Lim (sinkt)/t = kt/t = k
You could also use l'Hopital's rule and get the same answer.
