If θ = 45 degree, then what is the value of 2 cosec2 θ + 3 secc2 θ ?
Answer & explanation
Correct answer: option 1
2 cosec2 θ + 3 secc2 θ
cosec 45° = sec 45° = 2
2 cosec² 45° + 3 sec² 45° = 2 x 4 + 3 x 4 = 20
If θ = 45 degree, then what is the value of 2 cosec2 θ + 3 secc2 θ ?
Correct answer: option 1
2 cosec2 θ + 3 secc2 θ
cosec 45° = sec 45° = 2
2 cosec² 45° + 3 sec² 45° = 2 x 4 + 3 x 4 = 20
