ArcTan A Solution

STEP 0: Pre-Calculation Summary

Formula Used

ArcTan A = 1/3*atan(((3*Value A)-Value A^3)/(1-(3*Value A^2)))
tan^-1 A = 1/3*atan(((3*A)-A^3)/(1-(3*A^2)))
This formula uses 2 Functions, 2 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
atan - Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle., atan(Number)

Variables Used

ArcTan A - (Measured in Radian) - ArcTan A is the measure of the principal angle obtained by taking the inverse trigonometric tangent function value of the given real number A.
Value A - Value A is any real number that can be used for inverse trigonometric calculations.

STEP 1: Convert Input(s) to Base Unit

Value A: 3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

tan^-1 A = 1/3*atan(((3*A)-A^3)/(1-(3*A^2))) --> 1/3*atan(((3*3)-3^3)/(1-(3*3^2)))

Evaluating ... ...

tan^-1 A = 0.201848221201657

STEP 3: Convert Result to Output's Unit

0.201848221201657 Radian -->11.5650511770802 Degree (Check conversion here)

FINAL ANSWER

11.5650511770802 ≈ 11.56505 Degree <-- ArcTan A

What is Inverse Trigonometry?

Inverse Trigonometry is a branch of mathematics that deals with the inverse functions of trigonometric functions sine(sin), cosine(cos), tangent(tan), secant(sec), cosecant(cosec) and cotangent(cot). These functions (arcsine, arccosine, arctangent, arcsecant, arccosecant and arccotangent) take the resulting value of a trigonometric function and find the original angle that produced that value. In other words, it allows us to find the angle of a right triangle given the ratios of its sides.
