You cannot because cot(0) is not defined, neither is cosec(0).
Three lefts make a right.
Two wrongs don't make a right...but 3 rights make a left!
If you turn right three times, you will be facing the direction that was originally to your left. I'm not really sure what this has to do with the first part of your question, though.
you do left right left right keep doing it
it shirts left and right both sides.
move the reins to the right to make the horse turn right. move the reins to the left to make the horse go left. Not just by moving them but also by pulling them from left to go left and right to go right
Think of a compass rose, where you're facing north. Turn right 3 times, so you're facing the west, which is the left. Or, if you start in a neutral position, and consider each turn to be worth rotating 180o, then turning right 3 times would be facing right and then rotating (clockwise or counter-clockwise) 360o 3 times would end up pointing you to your left.
You have to be behind the cows/horses at all times and pretty much guide them to where you want them to go. (Go to the left of the herd to make them go right, and going to the right of the herd makes them go left)
when you hold up your left hand in an L shape, it will make an L, but if you do it with your right, it will make a backwards L.
make three rights to make a left. haha.
The saying is 2 lefts don't make a right. 3 rights do not make a left.
space up space up left right left right to make him DIE!
