`(1)/(sec A-tan A)=sec A+tan A`

Prove that (1+sec A-tan A)/(1+sec A+tan A)=1-sin A/(cos A)

sqrt((sec A-tan A)/(sec A+tan A))=?

Prove: (sec A-tan A)/(sec A+tan A)=(cos^(2)A)/((1+sin A)^(2))

(sec A+tan A-1)(sec A-tan A+1)=2tan A

If (sec A+tan A)(sec B+tan B)(sec C+tan C)=(sec A-tan A)(sec B-tan B)(sec C-tan C) prove that the value of each side is +-1

(sec A+tan A)(sec B+tan B)(sec C+tan C)=(sec A-tan A)(sec B-tan B)(sec C-tan C Prove that each of the side is equal to +-1

If (sec A+tan A)(sec B+tan B)(sec C+tan C)=(sec A-tan A)(sec B-tan B)(sec C-tan C then each side is equal to

sec A+tan A=3rarr sec A=
