[sec8A-1=tan8A],[sec4A-1]

Prove that: (sec4A-1)/(sec8A-1)=tan2A. cot8A

Prove that: (sec4A-1)/(sec8A-1)=tan2A. cot8A

(sec 8 A-1)/( sec 4A-1)=

(sec8A-1)/(sec4A-1)=(tan 8A)/(tan2A)

Prove that (sec8A-1)/(sec4A-1)=(tan8A)/(tan2A)

(sec8A-1)/(sec4A-1) is equal to (A) (tan2A)/(tan8A) (B) (tan8A)/(tan2A) (C) (cot8A)/(cot2A) (D) none of these

(sec8A-1)/(sec4A-1) is equal to (A) (tan2A)/(tan8A) (B) (tan8A)/(tan2A) (C) (cot8A)/(cot2A) (D) none of these
