An interactive step by step calculator and solver to find the angle between two vectors is presented. As many examples as needed may be generated along with their solutions and detailed explanations. 1) The angle $\theta$ between two vectors $\vec{u}$ and $\vec{v}$ is given by: $\theta= \arccos(\dfrac{\vec{u}\cdot \vec{v}}{||\vec{u}|| \cdot ||\vec{v}||})$2) The magnitude $||\vec{u}||$ of a vector $ \vec{u} $ given by its components as $\vec{u} = \langle a, b \rangle $ is given by $||\vec{u}||=\sqrt{a^2+b^2}$ 3) If $\vec{u} = \langle a, b \rangle $ and $\vec{v} = \langle c, d \rangle $ , the dot product $\vec{u}\cdot \vec{v} = a \cdot c + b \cdot d$ Solve each step below then click on "Show me" to check your answer.
