tan((2pi)/8)

Solution

tan (\frac{2 π}{8})

Solution

1

Solution steps

tan (\frac{2 π}{8})

Simplify:

\frac{2 π}{8} = \frac{π}{4}

\frac{2 π}{8}

Cancel the common factor:

2

= \frac{π}{4}

= tan (\frac{π}{4})

Use the following trivial identity:

tan (\frac{π}{4}) = 1

tan (\frac{π}{4})

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}

= 1

= 1
