How to find the exact value using the difference formula of two angles for tangent

👉 Learn how to evaluate the tangent of an angle in degrees using the sum/difference formulas. To do this, we first express the given angle as a sum or a difference of two (easy to evaluate) angles, then we use the unit circle and the Pythagoras theorem to identify the angles and obtain all the needed trigonometric function values of the angles. When we know the trigonometric function values of the two angles to be added or subtracted, we can apply the sum and difference formulas to evaluate the tangent of the given angle. 👏SUBSCRIBE to my channel here: https://www.youtube.com/user/mrbrianm... ❤️Support my channel by becoming a member:    / @brianmclogan   🙋‍♂️Have questions?
