Question

if tan teta =2 find sec teta ?​

Answer 1

$\huge{\fbox{\tt{Answer}}}$

The identity can be written in the form of (a-b)(a+b)=a^2 - b^2

Putting the given value of 2 in the equation we get a linear equations, which we add to the second equation.

It directly gives us the value of tan(theta)

I won't suggest using the inverse methods because tan(theta) can approach to many different values.
