Answer: csc -675 = √2

Explanation:

Keep adding 360 to find your reference angle.

-675 + 360 = -315

-315 + 360 = 45

Your reference angle is 45°

csc 45 =
(1)/(sin 45)

Remember your unit circle:

sin 45 =
(√(2) )/(2)

Substitute:

csc 45 =
(1)/((√(2) )/(2)) >Keep change flip

csc 45 = 2/√2 >Get rid of root on bottom

csc 45 =
(2√(2) )/(2)

csc 45 = √2

csc -675 = √2
