Question

If sec theta + tan theta =x, then sec theta =? ​

Answer 1

Answer:

I think it help for you,

Answer 2

Answer:

Step-by-step explanation:

seca+tana=x

Squaring

sec^2a-tan^2=1

(seca+tana)(seca-tana)=1

seca-tana=1/x....(1)

seca+tana=x...(2)

-----------------------------------

2seca=x+1/x

similarly

2tana=(x-1/x)

secatana=(x+1/x)(x-1/x)/4=(x^2-1/x^2)/4=(1/4)(x^2-1/x2)
