Put 4,7,3,5,2,2,7,4 to find the median

- -Put the numbers out from least to greatest:

2, 2, 3, 4, 4, 5, 7, 7, 
Now start crossing off until you get to the middle, so ill mark bold as what i cross of:

2, 2, 3, 4, 4, 5, 7, 7

now

2, 2, 3, 4, 4, 5, 7, 7

now

2, 2, 3, 4, 4, 5, 7, 7

Now you have 2 4's left

So you do: 

Therefore your answer is 4.

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)
