I have no idea but hopefully I helped you
Answer:It should be 49.365
Step-by-step explanation:
the series : 6/8 , -1/8 , 2/8 , -24/8 , -4/8 , 8/8
the ascending arrangement : -24/8 , -4/8 , -1/8 , 2/8 , 6/8 , 8/8
=
-3 , -1/2 , -1/8 , |1/4| , 3/4 , |-1|

Answer:
See proof below
Step-by-step explanation:
In trigonometry identity
tan^2 theta = sin^2 theta /cos^2 theta
cot^2 theta = cos^2 theta/sin^2 theta
csc^2 theta = 1/sin^2 theta
Substitute into the expression
(sin^2 theta /cos^2 theta )+ (cos^2 theta/sin^2 theta)/1/sin^2 theta
= [sin^4theta + cos^4theta/cos^2 theta sin^2 theta]÷(1/sin^2 theta)
= 1/cos^2 theta sin^2 theta÷(1/sin^2 theta)
= 1/cos^2 theta sin^2 theta * sin^2 theta/1
= 1/cos^2theta
= sec^2theta (Proved!)
