State True or False:
The value of the expression `(sin80^(@)-cos80^(@))` is negative.

Explanation

To determine whether the expression \( \sin 80^\circ - \cos 80^\circ \) is negative, we can follow these steps:

### Step 1: Rewrite the expression
We start with the expression:
\[ \sin 80^\circ - \cos 80^\circ \]
We can use the co-function identity which states that:
...
