Answer 2

The expression you provided, $cos(45^\circ) - sin(45^\circ)$, can be simplified using trigonometric identities.

Recall that $\cos(45^\circ) = \sin(45^\circ) = \frac{1}{\sqrt{2}}$, which is approximately 0.7071.

So, the expression becomes:

$\cos(45^\circ) - \sin(45^\circ) = \frac{1}{\sqrt{2}} - \frac{1}{\sqrt{2}} = 0$

Therefore, the correct option is:

б) 0
