If \( \Large \sin \theta +cosec \theta =2,\ then\ \sin^{2} \theta + cosec^{2} \theta \) is equal to

A) 1
B) 4
C) 2
D) none of these

Correct Answer:



C) 2

Description for Correct answer:

Given that, \( \Large \sin \theta +cosec \theta = 2 \)

On squaring both sides, we get

\( \Large \sin^{2} \theta +cosec^{2} \theta+2=4 \)

=> \( \Large \sin^{2} \theta + cosec^{2}\theta = 2 \)
