An online calculator that multiply a vector by a scalar is presented. The calculator gives the components of the vector , its magnitude and direction.
Let \( \vec{u} \) be a vector given in component form by
\[ \vec{u} = \langle u_1 , u_2 \rangle \]
The scalar multiplication of vector \( \vec{u} \) by a scalar \( k \) is defined by
\[ k \vec{u} = \langle k u_1 , k u_2 \rangle \]
Enter the components \( u_1 \), \( u_2 \), and the scalar \( k \). The outputs are the components of \( k\vec{u} \), its magnitude, and its direction (in degrees).
