Trigonometry: Sine Bar Applications discusses sine bars and the trigonometry required to use them. Sine bars are used when an angle needs to be machined, measured, or inspected. Sine bars are used ...

But Jackson and Johnson managed to prove the theorem using a result of trigonometry called the Law of Sines, dodging circular ...

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 ...

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 ...

Why? Because trigonometry itself is built upon the very theorem it seeks to prove. Any attempt at using sine, cosine, or tangent to verify Pythagoras’ equation seemed destined to rely on the ...
