1. Problem Description

The problem asks to find the value of tan(3π4)\tan(\frac{3\pi}{4}).

2. Solution Steps

We can rewrite 3π4\frac{3\pi}{4} as ππ4\pi - \frac{\pi}{4}.
Therefore,
tan(3π4)=tan(ππ4)\tan(\frac{3\pi}{4}) = \tan(\pi - \frac{\pi}{4})
We use the identity tan(πx)=tan(x)\tan(\pi - x) = -\tan(x).
So,
tan(ππ4)=tan(π4)\tan(\pi - \frac{\pi}{4}) = -\tan(\frac{\pi}{4})
Since tan(π4)=1\tan(\frac{\pi}{4}) = 1, we have
tan(π4)=1-\tan(\frac{\pi}{4}) = -1.
