Question

hi can anyone solve this

good answer= brainiest
bad answer = report

Answer 1

mark me as brainliest

Answer 2

(cosec^2 30 - sin^2 45 - sec^2 60

(cosec30)^2  = (2)^2  = 4

- (sin 45)^2  =  - (1/root 2)^2 = - 1/2

- (sec 60)^2  = - (2^2)  = -4

(cosec^2 30 - sin^2 45 - sec^2 60  = 4 - 1/2 - 4

                                           = -1/2
