Integral help - TakeHome Exam?

[Hunter_0132451]

I get that the unit circle is a big help to this problem however I am still having Problems working it all out

 

[Deleted member 4993]

sorry here is the problem, i figured out that there is some connection to the unit circle however I still need to get rid of the numerator with the restriction posted in the problem

Is this a Take home exam?

An honest cheater.

it is honestly more of homework than an actual take home quiz, basically this has been boggling my mind and I am just trying to wrap my head around the dividing and multiplying by 2 part that is it

i understand the second part however the first part is bothering me

 

[Hunter_0132451]

i would not ask for this if it was an actual exam I just need to figure something out, due to the hint he gave it seems to me like he wants me to turn the sqrt of three and the 1 before sin into sin pi/3 and cos pi/3

now i realize it could also be due to partial functions

this is what i got so far

All was good until the last line. Why did the angle go from x+pi/3 to x+pi/4
