Question

If sec A – tan A = k, then the value of sec A + tan A is........
jaIdi batao guys

Answer 1

Answer:

1/k

Step-by-step explanation:

there is a trigonometric identity which states that sec^2A-tan^2A=1

now if you observe this looks like m^2-n^2 which equals to (m+n)(m-n)

so here (secA-tanA)(secA+tanA)=1 (take time and observe you'll get it)

secA-tanA is given to be k so plugging this in the above equationwe get

(K)(secA+tanA)=1 so finally cross multiplying we get

secA+tanA=1/k

I REALLY HOPE THIS HELPED YOU
