With triangles and rules about them.
You can use trigonometry such as cos and tan
plane trigonometry spherical trigonometry
Anyone who knows more trigonometry than you and is able to convey that information effectively. A person with loads of qualifications does not necessarily make a teacher.
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
Hipparchus is the father of trigonometry.
It is a number - in trigonometry or elsewhere.
TRIGONOMETRY
Trigonometry is applied in construction and building, as trigonometry measures right angled triangles.
Plane trigonometry is trigonometry carried out in (on) a plane. This could be contrasted with spherical trigonometry, which is trigonometry carried out on the surface of a sphere. Certainly there are some other more complex forms of trig.
Trigonometry based on a unit circle and radians and trigonometry based on a right triangle.
trigonometry is very imr
