Answer: x= 30 because the elevated point is 25 degrees and if you add it with 110 and subtract it with 35 you get 110 + 25 = 135 and 35 - 25 = 15 135 + 15 = 150 and 180 - 150 = 30. so it is 30 degrees. (tell me if i was wrong cause i'm 90% sure this is it but i don't know.)
a. Recall that
For 
, we have
By integrating both sides, we get
If 
, then
so that
We can shift the index to simplify the sum slightly.
b. The power series for 
can be obtained simply by multiplying both sides of the series above by 
.
c. We have
