# Question: 1 sec11pi12 2 use the doubleangle identities to find tan2x...

###### Question details

1) sec(-11pi/12)

2) Use the double-angle identities to find tan(2x) if sec(x)=sqrt(6) and (sin(x) is greater than 0).

3) Use a half-angle identity to find cos(x/2) if csc(x) = -7 and (3pi/2 is less than x is less than 2pi).
