Explanation:
When we find the angle wrt to X axis we use cos theta for x axis and sin theta for Y axis. Similarly how can we get the trigonometric function of Z axis wrt Xaxis?
In a three dimensional "trigonometrical" situation we have three directional cosines instead.
cos2α+cos2β+cos2γ=1
where a diagonal ( instead of hypotenuse) makes these angles to (X,Y,Z) axes.
