Answer 2

Answer:

The value of cosec(1125) = $\sqrt{2}$

Step-by-step explanation:

Trigonometric values:

• By the right-angled triangle we have 6 different trigonometric ratios.

             Sinθ, Cosθ, Tanθ, Cosecθ, Secθ, Cotθ

• The trigonometric ratios have values for different angles

     Sin0° = 0, Sin30° = 1/2, Sin45° = 1/$\sqrt{2}$, Sin60° = $\sqrt{3}/2$, Sin90° = 1

     Cos0° = 1, Cos30° = $\sqrt{3}$/2, Cos45° = 1/$\sqrt{2}$, Cos60° = $1}/2$, Cos90° = 0

     Tan0° = 0, Tan30° = 1/$\sqrt{3}$, Tan45° = 1/$1$, Tan60° = $\sqrt{3}/2$, Tan90° = 1

     and we know

•    Sinθ = 1/Cosecθ, Cosθ=1/Secθ, Tanθ=1/Cotθ

        The remaining values can be known by the above values and relation.

       Also cosec(360+θ)° = cosecθ

   Now we will find the value of Cosec(1125)°

   Cosec(1125)° =  cosec(360+(720+45))°

                         =  cosec(720+45)°

                         = cosec(360+(360+45))°

                         = cosec(360+45)°

                         = cosec45°

                         = 1/sin45°

   Cosec(1125)° = $\sqrt{2}$

Hence the value of  Cosec(1125)° = $\sqrt{2}$
