Question

Dare anyone to solve this question.......


Answer must be in the digits....​

Answer 1

Step-by-step explanation:

5x = sec θ

(5/x) = tan θ

25x^2 = (sec θ)^2

(5/x)^2 = (tan θ)^2

25/x^2 = (tan θ)^2

25(x^2 - 1/x^2) = (secθ)^2 - (tan θ)^2

= 1 + (tan θ)^2 - (tan θ)^2

= 1

5(x^2 - 1/x^2) = 1/5
