Answer:
First, let's recall some usefull information:
- cot(x) = 1/tg(x) = cos(x)/sin(x)
- tan(x) = sin(x)/cos(x)
We also know that:
- cos(x - pi/2) = sin(x)
- sin(x - pi/2) = -cos(x)
Now we can use those relationships and get:
cot(x - pi/2) = cos(x - pi/2)/sin(x -pi/2) = sin(x)/-cos(x) = -tan(x)
So we have verified the identity, and explained step by step why the identity is true.
Process average or mean
is computed by dividing the total of the measurements made on the process by the number of measurements used to compute the total approximates. For example a coach wants to know if football players
who warm up before a game will score more points than those who don't warm up.
He will break the team up into two groups and make sure each player gets equal
time on the field. He will then count how many points each player makes during
the game. After counting them, add the scores of the group that he divided and
then divided it by the number of player in that group to get an average score
on teams that warm up or do not warm up before the game.
