MA005 section 4.7 Problem number 26. The question is the limit as x approaches infinity of (1-cos(3x))^x. The answer is given as 1. Shouldn’t their be no answer for this?

# Is this a mistake?

So does this mean it is a mistake?

Yes.

Unless I’ve made a mistake, the conclusion is that the function (1-cos(3x))^x has no limit

So is their a way to get Saylor to fix it?

Hi @student,

Please, be aware that I’m also just a fellow student here According to https://www.saylor.org/contact/ : “*The quickest way to get in touch with our staff is by email at contact@saylor.org. You can also use this form* [ FORM ]”

I have no connection with Saylor whatsoever. Some time ago I just stumbled across the website. I have few obligations that take up my time, so every so often I just answer a question. I think an appropriate solution to this sort of thing would be a preventative measure, e.g., both questions and solutions to them should be proof read before including them on examinations or problem sets.
