Solution

tan (19 π)

Solution

0

Solution steps

tan (19 π)

tan (19 π) = tan (0)

tan (19 π)

Rewrite

19 π

as

π \cdot 19 + 0

= tan (π 19 + 0)

Apply the periodicity of

tan

:

tan (x + π \cdot k) = tan (x)

tan (π \cdot 19 + 0) = tan (0)

= tan (0)

= tan (0)

Use the following trivial identity:

tan (0) = 0

tan (0)

tan (x)

periodicity table with

πn

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} tan (x) 0 \frac{3}{3} 13 \pm \infty - 3 - 1 - \frac{3}{3}

= 0

= 0
