## Understanding Vector Scalar Multiplication

Vector scalar multiplication involves multiplying a vector by a scalar (a single number). The result of the vector scalar multiplication is a new vector where each coordinate of the original vector is multiplied by the scalar.

If you have a vector $$$\mathbf{\vec{u}}=\langle u_1,u_2\rangle$$$ and you multiply it by a scalar $$$c$$$, the formula for the vector scalar multiplication is

$$c\mathbf{\vec{u}}=\langle cu_1,cu_2\rangle$$In the case of a 3D vector, if $$$\mathbf{\vec{v}}=\langle v_1,v_2,v_3\rangle$$$, the result of the vector scalar multiplication will be

$$c\mathbf{\vec{v}}=\langle cv_1,cv_2,cv_3\rangle$$## Example of Vector Scalar Multiplication

Let's say we have a vector $$$\mathbf{\vec{v}}=\langle 2,3,4\rangle$$$ and we want to multiply it by a scalar $$$3$$$. Using our vector scalar multiplication calculator, we can easily compute this:

$$3\cdot\langle 2,3,4\rangle=\langle 3\cdot 2,3\cdot 3,3\cdot 4\rangle=\langle 6,9,12\rangle$$The resulting vector is $$$\langle 6,9,12\rangle$$$.

### FAQ

#### What is the formula for vector scalar multiplication?

For a 2D vector $$$\mathbf{\vec{u}}=\langle u_1,u_2\rangle$$$ and a scalar $$$c$$$, the formula is $$$c\mathbf{\vec{u}}=\langle cu_1,cu_2\rangle$$$. For a 3D vector $$$\mathbf{\vec{v}}=\langle v_1,v_2,v_3\rangle$$$, the formula is $$$c\mathbf{\vec{v}}=\langle cv_1,cv_2,cv_3\rangle$$$.

#### Does multiplying a vector by a scalar change its direction?

Multiplying a vector by a positive scalar changes its magnitude (if the scalar doesn't equal $$$1$$$) but not its direction. If multiplied by a negative scalar, the resulting vector will have a different magnitude (if the scalar doesn't equal $$$-1$$$) and an opposite direction.

#### What is vector scalar multiplication?

Vector scalar multiplication is a mathematical operation where each coordinate of a vector is multiplied by a scalar (a single real or complex number). The result is a new vector.
