A) $\tan ^ { 2 } \theta$
B) $\csc ^ { 2 } \theta$
C) 1
D) $\sec ^ { 2 } \theta$

Question

Quizplus · Accepted Answer

The expression $\cot \theta \sec \theta \sin \theta$ simplifies to $\frac{\cos \theta}{\sin \theta} \cdot \frac{1}{\cos \theta} \cdot \sin \theta$, which simplifies further to $1$, making option C correct.
