This is an interesting pickle. So, on the brink of what seemed to be covering angular motion entirely, I realized that I had big misconceptions.
Like any sane individual would do in this case, I knocked out my Physics teacher with a brick, ran to the nearest computer and logged into StackExchange Physic to ask my question.
However, there were some wrong answers. I upvoted a wrong answer. And now I can't take back my upvote. At the time of upvoting, I had assumed that the answer would be right due to the upvotes it had received, but now realize that I should've asked for citations.
So what do I do now? How can I take back my vote?
