# What is the identity of SEC and tan?

## What is the identity of SEC and tan?

The subtraction of the tan squared of angle from secant squared of angle is equal to one and it is called as the Pythagorean identity of secant and tangent functions.

## What is the trig identity for SEC?

Cosecant, Secant and Cotangent

Cosecant Function: | csc(θ) = Hypotenuse / Opposite |
---|---|

Secant Function: | sec(θ) = Hypotenuse / Adjacent |

Cotangent Function: | cot(θ) = Adjacent / Opposite |

**What is tan trig identity?**

Formulas for the tangent function can be derived from similar formulas involving the sine and cosine. The sum identity for tangent is derived as follows: To determine the difference identity for tangent, use the fact that tan(−β) = −tanβ.

**What is the identity for tangent?**

The tangent identity is just tan(x) = sin(x)/cos(x) (when defined), the definition of tangent.

### What is SEC and Cos and Tan?

Sine, Cosine and Tangent. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is. To calculate them: Divide the length of one side by another side

### What does sin, cos, and Tan mean in trigonometry?

Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is

**What are the six trig functions?**

The six trigonometric functions are called sine, cosine, tangent, cosecant, secant, and cotangent.

**What is SEC in trig?**

secant (sec) A trigonometric function of an angle equal to the reciprocal of its cosine, that is, sec x = 1/cos x. It is equal to the ratio of the length of the hypotenuse to that of the side adjacent to the angle. Secant is usually abbreviated as sec.
