Calculate the length AB. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). The length \(h\) is ...

Calculate the angle QPR. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). In the triangle the ...

Instead, the pair of students used a trigonometric rule called the Law of Sines, which does not rely on the Pythagorean theorem. Two people had previously proved the theorem using trigonometry ...

In December 2022, a high school in Louisiana challenged its students with a bonus math question that came with a $500 cash prize: Using trigonometry, they had to create a new proof of the Pythagorean ...

Ne’Kiya Jackson and Calcea Johnson have published 10 trigonometric proofs of the Pythagorean theorem, a feat thought impossible for 2,000 years.

The student's discoveries were confirmed by the math community this week after their proofs were published in the American ...

Using a trigonometry rule called the Law of Sines, the students showed that the "proof is independent of the Pythagorean trig identity sin2x + cos2x = 1." In their published paper, the duo stated ...
