I used Sin instead of Cos for a triangle.

I just spent the last half hour trying to find my error in a problem. I checked my physics, my calculations, everything looked fine. It ended up being the simplest mistake I could make. I used Sin instead of Cos for a triangle. What a waste of time, it's the simplest mistakes you have to watch out for..

Been there, done that, got the T shirt, washed it to the point of destruction, now it's a rag, used to wipe up after my mistakes!

LOL! Mistakes that cost lives or money are the ones you need to watch out for. In your case, you paid for laundry detergent, hot water and electricity and a ruined T-shirt.

Agreed, the lives ones are tricky mistakes if your in that position, I'm not at present.

the T shirt wasn't ruined by the mistake, but worn out from time passing, I'm old, Ya see.

Well, not for people in my school
The simplest mistakes they do are like :
2*(1/2) = 4
1/(1/2) = 1/2
1-2=1

And stuff like that, but that is in exams, so that is when they are in a hurry.
