Answer» ong>Step-by-step EXPLANATION: We have : LHS: \bold{ \huge{ \sqrt{ \frac{ \sec(a) - 1 }{ \sec(a) + 1 } }} + \sqrt{ \frac{ \sec(a) + 1 }{ \sec(a ) - 1 } }} sec(a)+1 sec(a)−1
+ sec(a)−1 sec(a)+1
\bold{ \huge{ \frac{ \sqrt{ \sec(a) - 1} }{ \sqrt{ \sec(a + 1 } }} + \bold{ \frac{ \sqrt{ \sec(a) + 1} }{ \sqrt{ \sec(a) - 1 } }}} sec(a+1
sec(a)−1
+ sec(a)−1
sec(a)+1
\bold{ \huge{ \frac{(sec \: a - 1) + (sec \: a + 1)}{ \sqrt{(sec \: a + 1)(sec \: a - 1)} }}} (seca+1)(seca−1)
(seca−1)+(seca+1)
\bold{ \huge{ \frac{2SEC \: a}{ \sqrt{ {sec }^{2}a - 1 } }}} sec 2 a−1
2seca
\bold{ \huge{ \ \frac{2sec \: a}{ \sqrt{ {tan}^{2} a} }}} tan 2 a
2seca
\bold{ \huge{ 2 \: sec \: a \times cot \: a}}2seca×cota \bold{ \huge( \frac{2}{cos \: a}} {\bold{ \huge\times \frac{cos \: a}{sin \: a} )}}( cosa 2
× sina cosa
) \bold{ \huge{ \frac{2}{sin \: a}}} sina 2
