The input "tan4" is incomplete. In order to determine the value of the tangent of 4, we need to know if the value is in degrees or radians.

If the value is in degrees, we can calculate the tangent of 4 degrees using a calculator or trigonometric table.

If the value is in radians, we can use the identity tan(x) = sin(x) / cos(x) to calculate the tangent of 4 radians.
