Question 806468
(( using unit circle and Trig Identities)) Consider theta= 7pi /4
 

What is the reference angle? (I think I already got that one Im just saying it in case for the next part)
Ans: pi/4
--------------------- 
1) what is the reference angle's csc theta?
Ans: csc(7pi/4) = -csc(pi/4) = -sqrt(2)/2
------------------------------------------------ 
2) what is 7pi/4 csc theta
Ans: (7pi/4)(csc(theta) = (7/pi/4)(csc(7pi/4) = (7pi/4)(-sqrt(2)/2)
----
= (-7sqrt(2)pi/8)
