WebMay 25, 2024 · I need to prove or disprove that in any acute $\triangle ABC$, the following property holds: $$\sin A + \sin B + \sin C \gt \cos A + \cos B + \cos C$$. To begin, I proved a lemma: Lemma. An acute triangle has at most one angle which is less than or equal to $\dfrac{\pi}{4}$.. Proof: WebThe three sides for triangle ABC shown above, written symbolically as ABC, are line segments AB, BC, and AC. A is formed when two sides of a triangle intersect. ABC has vertices at A, B, and C. ... This is true for any triangle. As an example, you can see from the side and angle measures given for ABC above, AB > BC. Based on this, we know that ...
