To find the angle between the vectors \(\vec{A} = \hat{i} + \hat{j} + \hat{k}\) and \(\vec{B} = -2\hat{i} - 2\hat{j} - 2\hat{k}\), we can use the formula for the dot product of two vectors: \[ \vec{A} \cdot \vec{B} = |\vec{A}| |\vec{B}| \cos(\theta) \] where \(\theta\) is the angle between the two vectors. ...
