Draw a right triangle. If arccos x/3 = theta, draw that triangle.

then [tex]\frac{x}{3}[/tex] is the cosine of [tex]\theta[/tex]

You can use the pythagorean theorem to find the sine of [tex]\theta[/tex]

[tex]\cos^2 \theta + \sin^2 \theta = 1[/tex]

The tangent of [tex]\theta[/tex] is [tex]\frac{sin \theta}{cos \theta}[/tex]
