What have you learned about the six trigonometric ratio?

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.

What is the importance of learning trigonometric ratios?

Definition. Trigonometry is a study of the relationship of angles, lengths, and heights. It helps in finding the angles and missing sides of a triangle with the help of trigonometric ratios. The angles are either measured in radians or degrees.

What are the six trigonometric ratios used for?

In greek ‘Trig’ means triangle and ‘metic’ is for measurement. The Trigonometric rations are used to express relationship between angles and sides of a right triangle ( a triangle with one 90° angle). The non-right angle is usually designated by a greek letter θ (theta).

How can you relate the concept of trigonometric ratio in your daily life?

Trigonometry is used to set directions such as the north south east west, it tells you what direction to take with the compass to get on a straight direction. It is used in navigation in order to pinpoint a location. It is also used to find the distance of the shore from a point in the sea.

What have you learned from trigonometry?

The study of trigonometry involves learning how trigonometric functions – such as the sine or cosine of an angle, for example – can be used to work out the angles and dimensions of a particular shape. They should also put these functions to use in practical exercises to help students develop their skills.

How useful are trigonometric ratios in dealing with real life situations?

Trigonometry can be used to roof a house, to make the roof inclined ( in the case of single individual bungalows) and the height of the roof in buildings etc. It is used naval and aviation industries. It is used in cartography (creation of maps).

What are the 6 trig ratios?

The 6 Trig Ratios For any right triangle, there are six trig ratios: Sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). Here are the formulas for these six trig ratios: Given a triangle, you should be able to identify all 6 ratios for all the angles (except the right angle).

What are trigonometric ratios and how to find them?

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle. The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle. How to Find Trigonometric Ratios?

How do you find the value of six trigonometric functions?

· Determine the six trigonometric ratios for a given angle in a right triangle. · Recognize the reciprocal relationship between sine/cosecant, cosine/secant, and tangent/cotangent. · Use a calculator to find the value of the six trigonometric functions for any acute angle.
