They saw it as half of a rectangle ... to say why this approach to trigonometry has not survived. Perhaps it went out of fashion because the Greek approach using angles is more suitable for ...

Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles. Trigonometry is found all throughout geometry, as every straight-sided shape may be ...

It is not possible to use trigonometry to calculate the angle \(y\) because the length ... The point O is in the centre of the length AC so OC is half of the length AC. The length OC is \(\frac ...

Associate Professor Wildberger says the trigonometry we know has its historical roots in the work of ancient astronomers, like Ptolemy, who studied the motion of planets. In this case, the angle ...

Yes, I just call it "trig" because I always misspell trigonometry. Maybe you can use the double angle formula and you don't have a problem with trig identities. It's very easy to do some of the ...

Trigonometry allows one to systematically convert between measurements of angles and measurements of length, a topic that has interested mathematical astronomers from antiquity. Ancient Greeks also ...
