Sin θ . Cot θ . Sec θ = A) 2 B) -1 C) 1 D) 0

1.	Sin θ . Cot θ . Sec θ = A) 2 B) -1 C) 1 D) 0
Answer» Correct option is: C) 1 Sin \(\theta\) . Cot \(\theta\) . Sec \(\theta\) = Sin \(\theta\) . \(\frac {cos\, \theta}{sin \, \theta}. \frac 1 {cos \, \theta }\) (\(\because\) cot \(\theta\) = \(\frac {cos\, \theta}{sin\, \theta}\) & sec \(\theta\) = \(\frac 1 {cos \, \theta }\)) = 1 Correct option is: C) 1

Answer»

Correct option is: C) 1

Sin \(\theta\) . Cot \(\theta\) . Sec \(\theta\) = Sin \(\theta\) . \(\frac {cos\, \theta}{sin \, \theta}. \frac 1 {cos \, \theta }\)

(\(\because\) cot \(\theta\) = \(\frac {cos\, \theta}{sin\, \theta}\) & sec \(\theta\) = \(\frac 1 {cos \, \theta }\))

= 1

Correct option is: C) 1
