No. It can be used on any triangle.
Trigonometry is engineering math, but If you are going to study something in physics, or science, (basically this is "applied science"), you will need lots of calculus. calculus appears a lot in "Stargate".

Trigonometric knowledge is critical for navigation. Nowadays, a lot of the process is computerised but that is simply a transfer of trigonometric knowledge from people to machines.
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
It is a number - in trigonometry or elsewhere.
TRIGONOMETRY
Hipparchus is the father of trigonometry.
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
Trigonometry is not important ever
