Alright, so EVP = ghosts, but not necessarily. I am a paranormal investigator and I am compiling a list of false positives and known, environmental phenomena. I do know some ways a non-anomalous phenomenon can appear anomalous when recorded, but I would like input from anyone even if it is stating the obvious.

Thanks!

Determine all significant features by hand and sketch a graph.

f(x)=sinx+cosx

basically, I need to find the first derivative of the function, get x-values, and determine whether increasing or decreasing. Then take a second derivative and determine whether it's concave up/down.

I remember asking my science teacher the question that if a magnet is pointed the negitive down and is in the north pole can it be weighted heavier then if its weighted on its opposite side, due to the reason that the magnetic pulls are going to repel each other and I never got an answer

Can you solve this?
Three men rent a hotel room. Each pays $10 for a total of $30 spent on the room. The next day the hotel owner tells the three men that they over paid for the room as it only costs $25. The three men tell the owner to give them each a dollar back and he can keep two dollars.

If you do the math, each man paid $9 a piece for the room for a total of $27. The owner kept $2 which brings the total to $29.

The question is where did the other dollar go?
