What are the six trigonometric functions for?
Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. 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).

What is the formula of trigonometry?
It says that c2, the square of one side of the triangle, is equal to a2 + b2, the sum of the squares of the the other two sides, minus 2ab cos C, twice their product times the cosine of the opposite angle. When the angle C is right, it becomes the Pythagorean formula.
What is sin equal to?
Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram). The cosine is equal to the adjacent side divided by the hypotenuse (adj/hyp). What is the sine of B in the diagram? Remember opp/hyp: the opposite side is b and the hypotenuse is c, so sin B = b/c.
What is the formula of sin Cos tan?
The value of the tan function for any angle θ in terms of sin and cos can be given using the formula, tan θ = sin θ/cos θ.
What are the basics of trigonometry?
There are three basic functions in trigonometry, each of which is one side of a right-angled triangle divided by another. You may find it helpful to remember Sine, Cosine and Tangent as SOH CAH TOA.
What are the 3 trigonometric functions?
There are three basic trigonometric ratios: sine , cosine , and tangent . Given a right triangle, you can find the sine (or cosine, or tangent) of either of the non- 90° angles.
What is SOH CAH TOA?
“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2) (3) Other mnemonics include.
What is the father of trigonometry?
The first trigonometric table was apparently compiled by Hipparchus, who is consequently now known as “the father of trigonometry”.
What are the 3 trigonometric ratios?

What are the real life applications of trigonometry?
Other uses of trigonometry:
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 is angle formula?
Angles Formulas at the center of a circle can be expressed as, Central angle, θ = (Arc length × 360º)/(2πr) degrees or Central angle, θ = Arc length/r radians, where r is the radius of the circle.

How do you convert sin to CSC?
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 .
Why sine is called sine?
The word sine comes from the Latin sinus, bosom, because early translators mistook the Arabic word for chord and thought it was the Arabic word for bosom. The “co-” prefix in cosine and cotangent simply stands for co-angle, the complementary angle. The cosine of an angle is the sine of its complementary angle.
What is sin a and sin B?
Simply, it states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle. In ΔABC is an oblique triangle with sides a,b and c , then asinA=bsinB=csinC .
What is Cosec formula?
The cosecant formula is given as follows: cosec A = hypotenuse / opposite side = AB / BC = c / a. We know that, sin A = opposite side / hypotenuse.
What is cos in math?
The cosine (often abbreviated “cos”) is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. And the tangent (often abbreviated “tan”) is the ratio of the length of the side opposite the angle to the length of the side adjacent.
What are the values of sin Cos tan?
Values of Trigonometric Ratios at Various Angles:
| Angles (in degrees) | 0° | 60° |
|---|---|---|
| Sin θ | 0 | √3/2 |
| Cos θ | 1 | 1/2 |
| Tan θ | 0 | √3 |
| Cot θ | ∞ | 1/√3 |
