$\sf The \: value \: of \: {sec}^{2} \: 60-1 \: is \: equal \: to \: 3$

$\sf We \: have$

_____________________________________

$\sf To \: find \: the \: of \: {sec}^{2} 60-1 =?$

$∴ {sec}^{2} 60 - 1$

_____________________________________

$\sf we \: know \: that$

${sec}^{2} 60 = 2 \\ {2}^{2} - 1 \\ = 4 - 1 \\ = 3$

$\sf ∴The \: value \: of \: {sec}^{2} \: 60-1=3$

$\sf ⇒Thus \: the \: value \: of \: {sec}^{2} \: 60-1 is \: equal \: to \: 3$
