arctan calculator online

Online arctan calculator, arc tangent function calculator, can calculate the angle through arctan(x) value, arc tangent function value calculation.
  (°)  
  (rad)  
The arc tangent arctan(x) function is the inverse function and inverse operation of tan(x), such as
arctan(y) = tan⁻¹(y) = x+kπ
where k values are in the range {..., -2, -1, 0, 1, 2, ...}

How many degrees is arctan1 equal to, what is arctanx equal to, and how to calculate it?
For example, the tangent of an angle of 45° is 1, and tan(45°) = 1
Then the arctangent of 1 is 45°
arctan(1) = tan⁻¹(1) = 45°
