**Does trigonometry help in real life?**

Trigonometry and its functions have an enormous number of uses in our daily life. For instance, it is used in geography to measure the distance between landmarks, in astronomy to measure the distance of nearby stars and also in the satellite navigation system.

**Can a plane be a triangle?**

Because a triangle is made up of three non co-linear points, a triangle can be classified as a plane itself.

## Is precalculus harder than trigonometry?

Consequently, some students have a steep learning curve upon entering precal and will feel like they are swimming in unchartered waters for a while. Now, most students agree that math analysis is “easier” than trigonometry, simply because it’s familiar (i.e., it’s very similar to algebra).

### What grade do you learn trigonometry?

junior year

In general, trigonometry is taken as part of sophomore or junior year math. In addition to being offered as its own course, trigonometry is often incorporated as a unit or semester focus in other math courses.

**What profession uses trigonometry?**

Trigonometry spreads its applications into various fields such as architects, surveyors, astronauts, physicists, engineers and even crime scene investigators.

**What is the difference between geometry and trigonometry?**

¤ Geometry is a main branch of mathematics, while trigonometry is a branch of geometry. ¤ Geometry is a study about properties of figures. Trigonometry is a study about properties of triangles.

## What are some examples of trigonometric formulas that are similar to plane?

Furthermore, most formulas from plane trigonometry have an analogous representation in spherical trigonometry. For example, there is a spherical law of sines and a spherical law of cosines.

### How do you solve the plane trigonometry problem?

Plane trigonometry. In many applications of trigonometry the essential problem is the solution of triangles. If enough sides and angles are known, the remaining sides and angles as well as the area can be calculated, and the triangle is then said to be solved. Triangles can be solved by the law of sines and the law of cosines.

**What is the difference between plane and spherical trigonometry?**

As was described for a plane triangle, the known values involving a spherical triangle are substituted in the analogous spherical trigonometry formulas, such as the laws of sines and cosines, and the resulting equations are then solved for the unknown quantities. Many other relations exist between the sides and angles of a spherical triangle.
