of a triangle. It states that the ratio of the difference between the lengths of two sides to the tangent of the difference between the corresponding angles in a triangle is equal to the ratio of the sum of the lengths of the sides to the tangent of the sum of the corresponding angles....
It's easy to prove the first equation from the properties of the right triangle with side lengths111andxxx, as we perfectly know that the sum of angles in a triangle equals180°180\degree180°. Subtracting the right angle, which is90°90\degree90°, we're left with two non-right angles...
Finally, here is an easier proof of the identities, usingcomplex numbers: Proof 3 Tangent of the Sum and Difference of Two Angles We have the following identities for the tangent of the sum and difference of two angles: tan(α+β)=tanα+tanβ1−tanαtanβ\displaystyle...
The relations between the sides and angles of a right-angled triangle give us important functions that are used extensively in mathematics. Additionally, these are called trigonometric functions. Answer and Explanation: We have been given the trigonometric expression: ...
