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.
How to Calculate Value of ArcTan A?
Value of ArcTan A calculator uses ArcTan A = (1/3)*atan(((3*Value A)-Value A^3)/(1-3*(Value A^2))) to calculate the ArcTan A, Value of ArcTan A formula is defined as the measure of the principal angle obtained by taking the inverse trigonometric tangent function value of the given real number A. ArcTan A is denoted by tan^{-1} A symbol.
