Tangent is shortly referred as tan, and its one among the commonly used trigonometric function. In right angled triangle, it is opposite side over the adjacent side. It can be found by dividing the length of the opposite side divided by the length of the adjacent side. tan(-degrees) = -tan(degrees) is the common formula used for tangent function. Online trigonometric tangent tetra angle identity calculator which is used to find the tetra angle identity for tangent (tan) from the known angle value.

#### Formula:

tan 4α = (4 tanα - 4 tan3α ) / (1 - 6tan2α + tan4α) Where, tan = Tangent α = Angle

### Example:

If α is 20 degrees, then Tangent Tetra Angle?

#### Solution:

tan 4α = (4 tanα - 4 tan3α ) / (1 - 6tan2α + tan4α)
= (4 tan 20 - 4 tan320 ) / (1 - 6tan220 + tan420)
= 5.6479 °
