Trigonometry in C#

Constructing a program using the Math. trigonometry functions, I was testing it and the results are different to using the scientific calculator, why is this or have I done something wrong?

Console.WriteLine(Math.Sin(35));

-0.428182669496151

Calc: sin(35)

0.57357643635104609610803191282616

Hello I don't know for your calculator, but for Math.Sin, the angle must be in radians. In your calculator I think it's calculated from a degree unit.

EDIT : It was the problem

0.57357643635104609610803191282616 = sin(35) when 35 are degree

-0.428182669496151 = sin(35) when 35 are radians
