By What are the 6 trig functions?
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 equal to Cosθ?
cosθ is equal to adjacent side over hypotenuse that is cosθ= Hypotenuse Adjacentside. Here, in the given figure, opposite side AB=10, adjacent side BC=24 and the hypotenuse AC=26, therefore, sinθ and cosθ can be determined as follows: sinθ= Hypotenuse Oppositesid = ACAB.
What is equal to Tanθ?
⇒ θ = nπ + ∝, where n ∈ Z (i.e., n = 0, ± 1, ± 2, ± 3,…….) Hence, the general solution of tan θ = tan ∝ is θ = nπ + ∝, where n ∈ Z (i.e., n = 0, ± 1, ± 2, ± 3,…….) Note: The equation cot θ = cot ∝ is equivalent to tan θ = tan ∝ (since, cot θ = 1/tan θ and cot ∝ = 1/tan ∝).
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 are the 3 basic trig 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 sin θ?
Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse . No matter the size of the triangle, the values of sin(θ) and cos(θ) are the same for a given θ, as illustrated below.
How do you go from sin to cos?
Definition of cosine
- cos θ = sin (90° – θ).
- cos θ = sin (π/2 – θ).
- As mentioned before, we’ll generally use the letter a to denote the side opposite angle A, the letter b to denote the side opposite angle B, and the letter c to denote the side opposite angle C.
- Also, cos A = sin B = b/c.
- a2 + b2 = c2
- a2/c2 + b2/c2 = 1.
What is equal to Tanθ which side?
45 Degree. Explanation: Tan θ = Opposite / Adjacent.

Can you use SOH CAH TOA any triangle?
Q: Is sohcahtoa only for right triangles? A: Yes, it only applies to right triangles. A: They hypotenuse of a right triangle is always opposite the 90 degree angle, and is the longest side.
What is Cotangent formula?
The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . 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 .
