Express tan -82 as a function of the reference angle.

tan(278)
Explanation:The given trigonometric expression is:
tan (-82)
Note that:
To find the reference angle of a negative angle, you add 360° to it
Therefore:
tan(-82) = tan(-82+360)
tan(-82) = tan(278)
tan(-82) expresed as a function of its reference angle is tan(278)
