Answer:
1 -√2
Step-by-step explanation:
![\tan(x/2)=\dfrac{1-\cos(x)}{\sin(x)}\\\\\tan\left(\dfrac{1}{2}\cdot\dfrac{7\pi}{4}\right)=\dfrac{1-\cos\dfrac{7\pi}{4}}{\sin\dfrac{7\pi}{4}}=\dfrac{1-\dfrac{1}{\sqrt{2}}}{-\dfrac{1}{\sqrt{2}}}=\boxed{1-\sqrt{2}}](https://tex.z-dn.net/?f=%5Ctan%28x%2F2%29%3D%5Cdfrac%7B1-%5Ccos%28x%29%7D%7B%5Csin%28x%29%7D%5C%5C%5C%5C%5Ctan%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%5Cdfrac%7B7%5Cpi%7D%7B4%7D%5Cright%29%3D%5Cdfrac%7B1-%5Ccos%5Cdfrac%7B7%5Cpi%7D%7B4%7D%7D%7B%5Csin%5Cdfrac%7B7%5Cpi%7D%7B4%7D%7D%3D%5Cdfrac%7B1-%5Cdfrac%7B1%7D%7B%5Csqrt%7B2%7D%7D%7D%7B-%5Cdfrac%7B1%7D%7B%5Csqrt%7B2%7D%7D%7D%3D%5Cboxed%7B1-%5Csqrt%7B2%7D%7D)
