How would you solve tan(335) without using a calculator? I got it to tan(25) but that's not one of the ones on our chart, and I'd use a sum or difference identity but we never learned one for tangent, if one exists.

I don't see a solution without a calculator.

Assuming the angles are in degrees,
tan (335) = tan 25
Use tan (a + b) = (tana + tanb)/[1  (tana*tanb)]
I don't see a suitable combination of a and b, either.
