If 0 < x < 45° and 45° < y < 90°, then which one of the following i

1.	If 0 < x < 45° and 45° < y < 90°, then which one of the following is correct?(a) sin x = sin y (b) sin x < sin y (c) sin x > sin y (d) sin x ≤ sin y
Answer» (b) sin x < sin y Since sin θ in cosec from θ = 0° to θ = 90°, i.e., where 0° < θ < 90° then 0 < sin θ < 1. ∴ sin x < sin y.

If 0 < x < 45° and 45° < y < 90°, then which one of the following is correct?(a) sin x = sin y (b) sin x < sin y (c) sin x > sin y (d) sin x ≤ sin y

Answer»

(b) sin x < sin y

Since sin θ in cosec from θ = 0° to θ = 90°, i.e., where

0° < θ < 90° then 0 < sin θ < 1. ∴ sin x < sin y.
