Question

If sec A + tan A=1/5, then find sec A- tan A.​

Answer 1

Answer:

5

Step-by-step explanation:

(a-b)(a+b)=a^2-b^2

We know that :- sec^2 A-tan^2 A=1

so, 1/5*(sec A-tan A)=1

sec A-tan A=5.

Answer 2

Step-by-step explanation:

(SecA+tanA)(secA-tanA)=(sec^2-tanA^A)

Now put the value..

(1/5)(secA-tanA)=1

secA-tanA=5...is correct...
