$\huge\underline\mathcal\red{Hey}$

Answer:

=> Tan A + cot A = sin A / Cos A + cos A / sinA

= (sin^2 A+ cos^2A )/sinA Cos A

= 1/sinA cosA

=(1/sinA )(1/cos A)

= secA cosecA

Answer 2

Answer:

$\cot \: a + \tan \: a = \csc \: a \times \sec \: a \\lhs \: \: \: \: \: \: \: \: \: \: \frac{ \cos \: a \: }{ \sin \: a } + \frac{ \sin \: a }{ \cos \: a} \\ \frac{ \sin {}^{2} a + \cos{}^{2} a }{ \sin \: a \: \cos \: a } = \frac{1}{ \sin\: a \cos \: a } = \csc \: a \times \sec \: a$
