What is Trigonometry and what is it for?
Trigonometry is the branch of mathematics that studies the relationship between the sides and angles of triangles. It deals with the functions associated with angles, called trigonometric functions (or circular functions) sine, cosine, tangent, secant, cosine, cotangent.
What is trigonometry?
Trigonometry is a branch of mathematics, whose etymological meaning is «the measurement of triangles». In general terms, trigonometry is the study of trigonometric ratios: sine, cosine; tangent, cotangent; secant and cosecant.
What is the field of study of trigonometry?
Trigonometry studies the relationships that exist between the sides of a triangle and its angles. These can extend to any angle even if they are not part of a triangle.
What types of angles does trigonometry study?
Trigonometry is an important branch of mathematics devoted to the study of the relationship between the sides and angles of a right triangle and a circle.
What is the classification of trigonometry?
Spherical Trigonometry: That part of Trigonometry that deals with spherical triangles. Plane Trigonometry: That part of Trigonometry that deals with triangles in the plane. Trigonometry: It is the part of mathematics that has as its object the study of the relationships between the angles and the sides of a triangle.
What are the classes of trigonometry?
There are four types of trigonometry used today, including core, planar, spherical, and analytic. Core trigonometry is concerned with the relationship between the sides of a right triangle and its angles.
What are the two branches into which trigonometry is divided?
The two fundamental branches of trigonometry are plane trigonometry and spherical trigonometry. It is mainly concerned with solving plane triangles. To do this, the trigonometric ratios of the angles are defined and the relationships between them are studied.

How to find the 6 trigonometric ratios of a right triangle?
In this right triangle, the trigonometric ratios with respect to alpha (α) are defined as:
- Breast. Sine is the ratio (division) between the leg opposite the angle and the hypotenuse.
- Cosine. cosine, is the ratio (division) between the leg adjacent to the angle and the hypotenuse.
- Tangent.
- Cosecant.
- Drying.
- Cotangent.
How to find the trigonometric ratios of an angle?
The trigonometric ratios of any angle can be calculated using a scientific calculator. The calculator allows you to perform calculations with degrees (degrees, minutes and seconds) or radians and calculate the cosine, sine and tangent with keys to the image below.
How to get the trigonometric functions?
trigonometric ratios
- The sine of an angle α is defined as the ratio between the opposite leg (a) and the hypotenuse (c).
- The cosine is defined as the ratio between the contiguous leg or adjacent leg (b) and the hypotenuse (c).
- The tangent is the ratio between the opposite leg (a) and the contiguous leg or adjacent leg (b).
What is the sine cosine and tangent of a triangle?
The sine, cosine, and tangent of an acute angle of a right triangle are ratios of two of the three legs of a right triangle. The sine of an angle is the ratio of the length of the opposite leg of the angle divided by the length of the hypotenuse.
What is the sine of a triangle?
The sine of angle B is the ratio of the leg opposite the angle to the hypotenuse. It is denoted by sin B.
What is the cosine of a triangle?
His name is abbreviated cos. In trigonometry, the cosine of an angle of a right triangle is defined as the ratio between the leg adjacent to that angle and the hypotenuse: This ratio does not depend on the size of the chosen right triangle but is a function dependent on the angle.
What is a tangent in a triangle?
The tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle that contains that angle.
How is the tangent of a triangle calculated?
Three functions, the same idea….Sohcahtoa.
Soh… Sine = Opposite / Hypotenuse …cah… Cosine = Adjacent / Hypotenuse …toa Tangent = Opposite / Adjacent
How to get the tangent?
Tangent (abbreviated as tan) is understood as the relationship that exists between both legs (that is, the adjacent leg and the leg opposite the angle). It is obtained by dividing the values of both. It can also be obtained by relating the values of sine and cosine.
How to find the tangent of a fraction?
tan x = sin x / cos x Which means that the tangent of an angle (tan x) will be the number resulting from dividing the sine (sin x) by the cosine (cos x).
How to calculate the degrees of a tangent?
To express the arctangent in degrees, multiply the result by 180/PI( ) or use the DEGREES function.
What is the value of the 45 degree tangent?
The tangent of 45 degrees or π/4 radians is exactly equal to one. The tangent of an angle is defined from a right triangle. That is, the tangent of 45 degrees or π/4 radians is equal to one.
What is the tangent of 40 degrees?
