If sec θ - cos θ = 14 and 14sec θ = x, then the value of x is _________.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. tan2 θ
We have 14sec θ = x
Thus, 14 = x/sec θ
Putting this value of 14 in other equation we get,
x = sec2θ - 1 (because sec θ = 1/cos θ)
And, we know sec2θ - 1 = tan2 θ
