Question

Find the value of cosec² 30°- cot² 30°​

Answer 1

Answer:

1

Step-by-step explanation:

cosec = hypotenuse / opposite side

cosec = 1/ 1/2 = 2

cosec^2 = 2^2 = 4

cot = adjacent side/ opposite side

cot =(root 3/2) / (1/2)

cot =  root 3

cot^2 = 3

therefore, cosec^2 30°- cot^2 30° = 4-3 = 1
