Question

an=nsin(10/n)
solution from the textbook says 10

Answer 1

lim as n approaches infinity sin(10/n)/(1/n) is how i would rewrite it.
usually if it was sin(1/n)/(1/n) then i can use x=1/n let n approach infinity would mean x approaches zero
since sin(x)/x as x approaches zero would equal 1 then sin(1/n)/(1/n) would be one
is the method to solve this kind of the same as the one i have posted above?
