What are the six trigonometric formulas?
Trigonometric Ratios
- The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
- sin C = (Side opposite to ∠C)/(Hypotenuse) = AB/AC.
- cos C = (Side adjacent to ∠C)/(Hypotenuse) = BC/AC.
What are the six functions of trigonometry?
There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
How do you find Sec C in trigonometry?
The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
What are the two types of trigonometry?
Core trigonometry deals with the ratio between the sides of a right triangle and its angles. Plane trigonometry calculates the angles for plane triangles, and spherical trigonometry is used to calculate the angles of triangles that are drawn on a sphere.
How many types of trigonometry are there?
six different types
In mathematics, there are a total of six different types of trigonometric functions: Sine (sin), Cosine (cos), Secant (sec), Cosecant (cosec), Tangent (tan) and Cotangent (cot).
What are the 3 basic trigonometric identities?
There are three basic trigonometric ratios: sine , cosine , and tangent .
What is CSC trigonometry?
In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length of the side opposite the angle. The abbreviation is csc. csc θ = hypotenuse / opposite. It is not commonly used, and is equal to 1/sine.
What are the three important characteristics of trigonometry?
Trigonometry Identities. The three important trigonometric identities are: sin²θ + cos²θ = 1; tan² θ + 1 = sec² θ; cot ² θ + 1 = cosec² θ; Euler’s Formula for trigonometry. As per the euler’s formula, e ix = cos x + i sin x. Where x is the angle and i is the imaginary number.
What are the topics in class 10 trigonometry?

What are the six trigonometric functions used to find ratios?
The six trigonometric functions can be used to find the ratio of the side lengths. The six functions are sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). Below you will see the ratios formed by these functions. sin ? = � �
What are the trigonometric formulas or identities?
