Let $\vec{a}$ and $\vec{b}$ be two non-zero vectors inclined at an angle $\theta$. Then the scalar product or dot product of two vectors, $\vec{a}$ with $\vec{b}$ is denoted by $\vec{a}$.$\vec{b}$ and is defined as, $\vec{a}$.$\vec{b}$ = $|\vec{a}||\vec{b}|cos\theta$  If $\vec{a}$ = $a_1\hat{i}+a_2\hat{j}+a_3\hat{k}$ and $\vec{b}$ = $b_1\hat{i}+b_2\hat{j}+b_3\hat{k}$. Then $\vec{a}$.$\vec{b}$ = $a_1b_1+a_2b_2+c_1c_2$ Properties of Dot Product of Two

Cross Product of Vectors Formula : Let $\vec{a}$ & $\vec{b}$ are two vectors & $\theta$ is the angle between them, then cross product of vectors formula is, $\vec{a}$ $\times$ $\vec{b}$ = |$\vec{a}$||$\vec{b}$|sin$\theta$$\hat{n}$ where $\hat{n}$ is the unit vector perpendicular to both $\vec{a}$ & $\vec{b}$. Properties of Vector Cross Product : (i) $\vec{a}$ $\times$ $\vec{b}$ =

Here you will learn what is unit vector, representation of unit vector, formula for unit vector and how to find the unit vector with examples. Let’s begin – What is a Vector ? A quantity that has both magnitude & direction is called a vector. A vector that has magnitude of 1 is called a
