ns looked at the equipment of sin(2x)/x as x philosophies infinity (https://www.stillproud.orgway.com/popular-problems/Calculus/569134).

You are watching: Limit of sinx as x approaches infinity

I know -1

Also, if you usage the L"hopital ascendancy instead of squeeze theorem for sin(2x)/x you acquire it is equal to border of 2sin(2x)/1. 2sin(2x)/1 as x goes to infinity is undefind ! therefore squeeze theorem states the initial limit is 0 while the l Hoptial ascendancy says the initial limit is undefined. Which rule do girlfriend use?

Thank girlfriend so much.

The easiest use the the squeeze theorem for $lim_x opminftyfracsin f(x)x$ is $-frac1xlefracsin f(x)xlefrac1$, therefore the limit is $0$.

If you space taking $x o infty$ girlfriend don"t have to worry around the instance where $x$ is negative.

You cannot use l"Hopital"s rule since the numerator $sin(2x)$ does not have a limit as $x o infty$.
