Measure the magnitudes and directions of the resulting vectors. Use trigonometry. Some rules of trigonometry, such as the law of Pythogoras, apply only for right triangles. However, there are other, ...

In a new peer-reviewed study, Ne'Kiya Jackson and Calcea Johnson outlined 10 ways to solve the Pythagorean theorem using trigonometry, including a proof they discovered in high school.

Calcea Johnson and Ne'Kiya Jackson surprised the math world when, as seniors in high school, they produced innovative solutions to a 2,000-year-old puzzle.

It may be necessary to use Pythagoras' theorem and trigonometry to solve a problem. The trigonometric ratios can be used to solve 3-dimensional problems which involve calculating a length or an ...
