Question

if sec o + tan o = m & seco -tano=n the value of mn_______​

Answer 1

Answer:

mn = 1

Step-by-step explanation:

$sol {}^{n}$

$\sec(0) + \tan(0) = m \\ and \: \sec(0) - \tan(0) = n$

$= >( \sec(0) + \tan(0))( \sec(0) - \tan(0)) = m \times n$

$= >sec {}^{2}0 - tan {}^{2} 0 = mn$

$= > 1 = mn \: (since \: 1 + tan {}^{2}0 = sec {}^{2} 0)$

So, mn = 1
