Tính lim (sin3x/4n -1)

To find the limit of the expression (sin(3x)/(4n - 1)) as n approaches infinity, we can use the limit properties and the fact that sin(3x) is bounded between -1 and 1.

As n approaches infinity, the denominator 4n - 1 also approaches infinity. Therefore, we can ignore the constant term -1 in the denominator.

Now, we have the expression sin(3x)/(4n). Since sin(3x) is bounded between -1 and 1, and the denominator 4n approaches infinity, the overall expression approaches 0.

Therefore, the limit of (sin(3x)/(4n - 1)) as n approaches infinity is 0.
