Answer 2

Answer:

-π/3

Step-by-step explanation:

u have to find the principal value

cosec(-14π/6)

cosec(-7π/3)

cosec(-7π/3+2π).... adding 2π will give same answer

cosec(-π/3)

so cosec-1 will give -π/3

this is happening because if we take inverse of a function it must be bijective and trigonometric functions are bijective over a fixed domain
