Answer 2

Answer:

$cosec \: o \times sec \: o$

Explaination:-

$\cot \: o + \tan \: o\\ \frac{ \cos \: o}{ \sin \: o \: } + \frac{ \sin \: o }{ \cos \: o } \\ \frac{ \cos {}^{2} o \: + \: \sin {}^{2} o }{ \sin \: o \: \times \cos \: o } \\ as \: we \: know \: (\cos {}^{2} o \: + \: \sin {}^{2} o )\: = 1 \\ \frac{1}{ \sin \: o \: \times \cos \: o } \\ \frac{1}{ \sin \: o } \times \frac{1}{ \cos \: o} \\ \\ \cosec \: o \: \times \: \sec \: o$
