Question

If the theta =45 , then find the value of cosec square theta

Answer 1

Answer:

theta=45°

cosec theta =1/sin theta

then

cosec 45°=1/sin45°

sin45= 1/√2

cosec45 square =(√2)²

2 this is ur answer mark as brainliest

Answer 2

Answer:

theta = 45° (given)

cosec theta = 1/sin theta (identity)

THEN,

cosec 45° = 1/ sin 45

sin 45 = 1/√2

cosec 45 ^2= √2

=2

so , the value of cosec ^2 theta = 2
