Working with trigonometric relationships in degrees Trigonometric functions can have several solutions. Sine, cosine and tangent all have different positive or negative values depending on what ...

To get the other solution, we need to go back to our quadrants and use the appropriate rule: Therefore since the trig equation we are solving is sin and it is positive (0.5), then we are in the ...

Now, a new article not only proves that theorem—which relies on the Law of Sines—but puts forth four more trigonometric proofs, as well as five additional proofs outside of trigonometry.
