Answer 2

The value of $\sec^2 60-1$ is equal to 3.

Step-by-step explanation:

We have,

$\sec^2 60-1$

To find, the value of $\sec^2 60-1$ = ?

∴ $\sec^2 60-1$

We know that,

$\sec 60$ = 2

= $2^2-1$

= 4 - 1

= 3

∴ The value of $\sec^2 60-1$ = 3

Thus, the value of $\sec^2 60-1$ is equal to 3.
