Do you mean

Sin(pi/7) or {Sin(pi)} / 7

Note the position of the '7' be it inside or outside the Sine Function.

Clarity is needed, in the position of the '7'.

However,

Maker sure you calculator is in 'Radian' mode.

Sin(pi/7) =

Sin(0.44879895...)

=0.0078329....

or

{Sin(pi)}/7 = 0.054803665.../7

= 0.007829095021....

Note the two different answers.
