Problem 77Multiple Choice

Find out if the given statement is true or false. If the statement is false, state the reason.
1 +cot² (30°) = csc² (30°)

A

True

B

False because 1 +cot² (30°) = 2; csc² (30°) = 4

C

False because 1 +cot² (30°) = 4; csc² (30°) = 2

D

False because 1 +cot² (30°) = √2; csc² (30°) = 2
