Here is a suggestion. Use exp(x)=ex to simplify notation.I am stuck at the last step and I don't know how to go on.Can someone help me?What do I do from the last step?View attachment 12111
Jomo, x→∞limcos(x1)=1.Personally, I would use the squeeze theorem.
If x is large enough (you find out how large), then 0<cos(1/x)< .5 (.5 can be replaced with any other positive number less than 1)
Yes, I do want to rethink that one. Thanks for pointing it out. Good job!Jomo, x→∞limcos(x1)=1.
