WebDec 20, 2016 · 7 Even though you can always get the tangent of a supplementary angle from the sine and cosine, it’s a time-saver to have a rule for the supplement of a tangent. The last problem’s solution suggested what that rule might be. Prove: tan(180° − A) = −tan A.. Proof: tan(180° − A) = sin(180° − A) / cos(180° − A). tan(180° − A) = sin A / (−cos A) ff9a3f03-56ef-4613-bdd5-5a41c1d07246ff99cc colorWebTrigonometry.
