Question

Whats the exact value of csc^-1(csc -315°) in radian form or fraction form?

Answer 1

Answer:
`(\pi)/(4)` radians

Step-by-step explanation:

csc⁻¹ (csc -315°)

csc⁻¹ and csc cancel out so you are left with -315°

-315° + 360° = 45°

Look at the Unit Circle to see that 45° =
`(\pi)/(4)` radians
