Calculate tan-1 in c# angles?

  • 772

I am trying to do the following calculation but nothing I do works for me

enter image description here

The calculation of tan-1(1)the result of the calculator is 45 gradosbut I can't get that result in C#.

Code:

Math.Tanh(1);// resultado = 0,761594155955765
Math.Atan(1);//resultado = 0,785398163397448
Math.Tan(1);//1,5574077246549

I suppose that I must carry out some more operation with one of them, but what operation and which one to use to obtain the result.

c#

    You have to use Math.Atan(Double) .

    According to Microsoft documentation

    returns

    Double

    Angle, θ, measured in radians , as -π/2 ≤θ≤π/2. Either NaN if dequal to NaN, -π/2rounded to double precision (-1.5707963267949) if dequal to NegativeInfinity, or π/2rounded to double precision (1.5707963267949) if dequal to

    Taking this into account, it can be seen that the problem occurs because you are looking to obtain the degrees and the function is returning radians.

    To get the result in degrees you should do the following

    Math.Atan(1) * 180 / Math.PI; // resultado 45
