It can mean that, but it doesn't always. Most often, I see the square brackets simply used for nested grouping symbols. For instance, rather than 1 /...
I'll assume that by Acos(x - B), you mean A * cos(x - B) and not the common notation for arccosine (aka inverse cosine). If that's the case, then my...
Most of your work is good, except for a few things. One, the Pythagorean Theorem a2 + b2 = c2 is about the sides of a triangle, not the angles. Two,...
I can't say as though I've seen the term "independent" used in this context before, but my best guess is that you're correct. If an expression can be...
What are your thoughts? What have you tried? For instance, your title says "Integration by Substitution." Which expression in x did you pick for your...
Well, it's true that equivalent sets have will always have the same cardinality, but that's not why they're equivalent. It's sort of like how planes...
Just adding this to the public record. This exact problem was also asked on AskMath over at Reddit (possibly by the OP? possibly by a classmate? The...
Oof! Can't believe I didn't notice this myself. I didn't real carefully enough I suppose. I had thought they were asking for a solution of the form y...
Erm, sorry, but I hope you'll bear with me, as I'm really having trouble deciphering what it is you're asking. I think you're asking about something...
The basic shape of the graph will stay the same, being that of 1/x, but the specific values for any given x will change according to the constant. It...
