---(1)
We know that:
---(2)
Comparing (1) and (2)
---- (3)
Using power series expansion for 


![=-[c+\sum\limits^{ \infty}_{n=0} (-1)^{n}\frac{x^{2n+1}}{2n+1}]](https://tex.z-dn.net/?f=%3D-%5Bc%2B%5Csum%5Climits%5E%7B%20%5Cinfty%7D_%7Bn%3D0%7D%20%28-1%29%5E%7Bn%7D%5Cfrac%7Bx%5E%7B2n%2B1%7D%7D%7B2n%2B1%7D%5D)


as

Hence,

Answer: They sold 68 tickets at the door
688-920= -2x= -232
2x=232/2=116
184-116=68
The answer is 589,918
Take 652203 and subtract 62,285 from that and you get 589,918
