1. Introduction to the Angle formed by the vector with coordinate axes: -

Embarking on a journey into vector mathematics, this blog delves into the art of determining the angles formed by a vector with the x, y, and z axes. Understanding these angles provides valuable insights into the orientation of vectors in three-dimensional space.
$\bold{Definition}$
When a vector is positioned in three-dimensional space, the angles it forms with the coordinate axes (x, y, and z) are crucial for understanding its spatial orientation. These angles are known as directional cosines.

2. What is the Formulae used?

The formula to calculate the angles ($\alpha, \beta, \gamma$) formed by the vector $\vec{A}$ = ai + bj + ck with the x, y and z axes respectively, is given by
$\bold{\alpha = cos^{-1}(\frac{a}{|\vec{A}|})}$
$\bold{\beta = cos^{-1}(\frac{b}{|\vec{A}|})}$
$\bold{\gamma = cos^{-1}(\frac{c}{|\vec{A}|})}$
where, $|\vec{A}|$ is the magnitude of the given vector.
For the formula to be applicable, the vector A must not be the zero vector, ensuring division by zero is avoided.

3. How do I calculate the Angle formed by the vector with coordinate axes?

$\bold{Step\space:1}$ Identify the components $A_x, A_y$ and $A_z$ of the vector $\vec{A}$.
