Question

if tanA + secA = x then secA =?​

Answer 1

Answer:

If. secA+tanA. = x……….(1). Then. secA=?

we know that:-

sec^2x-tan^2x=1

or. (secA-tanA)(secA+tanA)=1

or. (secA-tanA)(x)=1

or. secA. -tanA = 1/x…………….(2)

On adding eqn.(1) & (2)

2secA=(x+1/x)=(x^2+1)/x

or. secA= (x^2+1)/2.x. Answer.
