Answer:
![\Sigma(2n-1) \left \{ {{n=50} \atop {n=1}} \right. \hspace{5} n\in N](https://tex.z-dn.net/?f=%5CSigma%282n-1%29%20%5Cleft%20%5C%7B%20%7B%7Bn%3D50%7D%20%5Catop%20%7Bn%3D1%7D%7D%20%5Cright.%20%5Chspace%7B5%7D%20n%5Cin%20N)
Step-by-step explanation:
First, we need to find the sequence associated to the summation. As you can see the sum only takes odd numbers into account. Hence the sequence it is defined by:
![2n-1](https://tex.z-dn.net/?f=2n-1)
Where:
![n\in N](https://tex.z-dn.net/?f=n%5Cin%20N)
Now, we only need to find the limits of the summation:
Evaluating n=1
![2(1)-1=2-1=1](https://tex.z-dn.net/?f=2%281%29-1%3D2-1%3D1)
Evaluating n=50
![2(50)-1=100-1=99](https://tex.z-dn.net/?f=2%2850%29-1%3D100-1%3D99)
Therefore the summation can be written as:
![\Sigma(2n-1) \left \{ {{n=50} \atop {n=1}} \right.](https://tex.z-dn.net/?f=%5CSigma%282n-1%29%20%5Cleft%20%5C%7B%20%7B%7Bn%3D50%7D%20%5Catop%20%7Bn%3D1%7D%7D%20%5Cright.)
Well, if you look at your Unit Circle, as you should have one already, we know that 180 degrees is really π radians.
now, if 180 degree is π radians, how many degrees is it on 133π/72?
