The value of cos 25° – sin 25° is

positive but less than 1

positive but greater than 1

negative

Since, value of cos Θ decreases, from 0° to 90° and at 45° it is equal to the value of sin Θ.

Similarly, value of sin Θ increases from 0° to 90° and at 45° it is equal to the value of cos Θ.

For 0° < Θ < 45°, cos Θ > sin Θ
So, value of cos 25° – sin 25° is always positive but less than 1.
