| If \(\alpha, \beta, \gamma\) are the angles that a line makes with the positive direction of \(x,y,z\) axis respectively, then the direction cosines of the line are |
\(\sin \alpha, \sin \beta, \sin \gamma\) \(\cos \alpha, \cos \beta, \cos \gamma\) \(\tan \alpha, \tan \beta, \tan \gamma\) \(\cos^{2}\alpha, \cos^{2}\beta, \cos^{2}\gamma\) |
| \(\cos \alpha, \cos \beta, \cos \gamma\) |
| Recall definition |
