Question

Sin a/Cos a . Cot α =

A) Tan α

C) 1

B) Cota

D) -1

Answer 1

Correct option is: C) 1

\(\frac{Sin\, \alpha}{Cos\, \alpha} . Cot\, \alpha =\) \(\frac {sin \,\alpha}{cos \, \alpha}. \frac {cos \, \alpha}{sin \, \alpha} = 1\) ( \(\because\) cot \(\alpha\) = \(\frac {cos \, \alpha}{sin \, \alpha}\))

Answer 2

Correct option is: C) 1
