Step-by-step explanation:
but you let me choice, I choice B.
C. thats the only one that will give you the same price for the DVDS as well. they charge $14 for CDS and $19 for DVDS
1 + sec^2(x)sin^2(x) = sec^2(x)
This becomes
1+tan^2(x) = sec^2(x) which is an identity
You could
1 + sin^2(x)/cos^2(x) = sec^2(x)
then
cos^2(x) + sin^2(x) = cos^2(x)sec^2(x)
1 = 1
