What are the purpose of trigonometry?

Answer 1

Ang layunin ng trigonometrya ay upang lumikom ng mas maraming tumpak na sukat ng distansya bibigyan ng maliit na impormasyon tungkol sa mga anggulo o iba pang mga distansya. Ito ay ginagamit sa engineering, astronomiya, pagpaplano ng lungsod, pagbalangkas at pagdidisenyo, at construction.

The purpose of trigonometry is to gather as much accurate measurements of distances given little information about angles or other distances. It is used in engineering, astronomy, city planning, drafting and designing, and construction.

Trigonometry helps surveyors determine sides of a triangle which are either inaccessible or difficult to access. Knowing the length of a single base line enables the surveyor to define the other elements of the triangle by measuring the angle to the inaccessible points from accessible points.

Consequently the heights of trees and tall buildings can be determined by knowing the distance to the base of the tree or building. Similarly locations separated by, for example, rivers or busy roads can be determined by angular measurement from positions of known distance apart on the other side of the obstruction.

Survey control marks used for the mapping of countries were in the past established by triangulation from a known base line.

These days much of the survey control is undertaken using GPS equipment which uses satellite signals to determine positions on earth. However the theory behind the location of these positions also uses trigonometry and spherical trigonometry.

Usually it's used to find a missing angle or length of a right triangle. Of course there is more to trigonometry. Any way you can use sine, cosine, and tangent, to fine the missing angle or length

The purpose of this lesson is to review angle measures, right triangles, and the geometry of the unit circle.

Compute angles in radians and degrees and convert between the two.

Work with similar triangles.

Understand basic trigonometric functions.

Make simple computations for special angles.
