Answer:
cosec (810°) = 1
Step-by-step explanation:
cosec (810°)
We know that any angle greater than 360 = angle - 360x
= cosec (810 - 360x)°
[Where x is the highest possible value in which the equations evaluates to >= 0]
We can clearly see that 2 is the highest x value for which the equation evaluates to >= 0
= cosec (810 - 360*2)°
= cosec (810 - 720)°
= cosec (90)°
We know that cosec θ = 1/sin θ
= 1/sin (90)
We also know that sin (90) = 1
= 1/1
= 1
∴ cosec (810)° = 1
