Solution steps

tan (0.25 π)

= tan (\frac{1}{4} π)

Simplify:

\frac{1}{4} π = \frac{π}{4}

\frac{1}{4} π

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 π}{4}

Multiply:

1 π = π

= \frac{π}{4}

= tan (\frac{π}{4})

Use the following trivial identity:

tan (\frac{π}{4}) = 1

tan (\frac{π}{4})
