Question

cosec2(90−θ)+cos2(90−θ)−cot245 please help

Answer 1

\[cosec^{2}(90−θ)+\cos^{2}(90-\theta)−\cot^{2}45\]

Answer 2

@ganeshie8

Answer 3

looks up the "cofuntion identities" to get rid of the \(90-\theta\) part

Answer 4

\[cosec^{2}(90 degree−θ)+\cos^{2}(90degree −θ)−\cot^{2}45 degree\]

Answer 5

please find the value

Answer 6

sec^{2}90 degree+sin^{2}90 degree-cot^{2} 45 degree

Answer 7

0+1-1
