The obvious answer is the relationships between the sides and angles of triangles. Waves in the sea are an example of a sine wave. Tidal Experts and Meterologists alike use sine waves to help predict tides. Music will also emit waves that may often look like a sine wave and pure notes will look like sine or cosine waves. The speed of a swinging pendulum can be plotted as a sine wave as well as the sound of a tuning fork.
If you are in school and are studying trig then you are using trig in real life.
Surveying is all trig. Much trig in physics and engineering,
trig
cosine = adjacent/hypotenuse. It can be used as other trig functions can.
Trigonometry functions are used to work out the various properties of triangles.
If you are in school and are studying trig then you are using trig in real life.
That depends on your profession. If you are a math teacher, then you might use a lot of Trig. If you are an engineer, working with forces on any object from different directions, then you would use trig. Electrical engineers use trig. Surveyors use trig.

Geometry is a prerequisite for trigonometry. Trig is a prerequisite for higher math, which is going to be used throughout your life.
Your brain is constantly doing trig subconsciously when you see(unless you have only 1 working eye). When we see things to gain depth perception, and thus gauge distance that is trig.
I am a retired math/science teacher. I used trig every day to teach students.
Figuring out distances, diameters of large objects, and more. Trig is also used in careers.
Yes
Trigonometry is the study of triangles. Since you use triangles in quilting, technically trig is a part of quilt making. No quilt maker I have ever known has used trig (other than myself). Geometry is used more in quilt making than trig.
Trig identities are vital in upper level math. Anything involving the unit circle or triangles is completely based in the trig identities. Trig is used in many other fields, such as architecture, where the identities play a huge role.
Unless your future career lies in engineering or physics, it is unlikely you will use too much trig in your future life, but that does NOT mean that you shouldn't study it. The experience gained from studying trig will give you the reasoning skills used to solve unrelated problems. Also, working hard to do well in trig class will help give you the self-discipline you need to achieve your other goals.
Trig Palin's birth name is Trig Paxson Van Palin.
