comment Exclusions found but Solve and Reduce don't find exclusions
@Guesswhoitis. Thanks, that works. I had just thought of trying that before your comment, but thanks for the help. Any way to make the Cos[x]==0 exclusions a different ExclusionsStyle?

comment Problem with code from Stan Wagon's book
@Willinski . Yes, that is definitely a mistake, but my real question here is why do Refinement and ControlValue remain in blue, and why can I not find them in the documentation?

I agree, the sphere looks really cool. I've gotta try that. However, please see the update to my original post.

Nice answer, but see my update in my original post. I should have been more specific as to what I needed.

comment Limit problem calculating directional derivative
@MariusLadegårdMeyer. I am currently writing on notebook introducing the directional derivative for my students in the fall. I think this event, though bizarre, is actually (as you say) a fortunate event, because this example is going into the notebook with an explanation to the students on how to handle the situation. Thanks for all the help.

comment Limit problem calculating directional derivative
@Jens. Thanks for the quick answer. I performed each of your suggestions and both work, but this is a bizarre event. I have never experienced this before. This probably will be rare with the students, but when it happens, oh my goodness. Tough one to explain.
