Answer 2

Answer:

$\frac{1}{ \tan(a) + \cot(a) } = \frac{1}{ \frac{ \sin(a) }{ \cos(a) } + \frac{ \cos(a) }{ \sin(a) } } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{ \sin(a) \times \cos(a) }{ {sin}^{2} a + {cos}^{2}a } \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \sin(a) \times \cos(a)$

sin²A+cos²A= 1
