How to raise a number to an absolute value of another number in C#?

My problem is that I need to write a complex mathematical equation which has me raise x to the power of |y|, both numbers entered by user. I've tried using the code below, but it produces a CS7036 error:

There is no argument given that corresponds to the required formal parameter 'y' of 'Math.Pow(double, double)'

class Program
{
    static void Main(string[] args)
    {
        double x,y,z,v;
        Console.Write("x=");
        double.TryParse(Console.ReadLine(), out x);
        Console.Write("y=");
        double.TryParse(Console.ReadLine(), out y);
        Console.Write("z=");
        double.TryParse(Console.ReadLine(), out z);
        v=(1+Math.Pow(Math.Sin(x+y)))/
            Math.Abs(x-2*y/(1+x*x*y*y))*Math.Pow(x,Math.Abs(y))+
            Math.Pow(Math.Cos(Math.Atan(1/z)),2);
        Console.Write("v="+v);
        Console.ReadKey();
    }
}

Update

(After the OP posted the code)

Code

        double x,y,z,v;
        Console.Write("x=");
        double.TryParse(Console.ReadLine(), out x);
        Console.Write("y=");
        double.TryParse(Console.ReadLine(), out y);
        Console.Write("z=");
        double.TryParse(Console.ReadLine(), out z);
        v=(1+Math.Pow(Math.Sin(x+y)))/
        Math.Abs(x-2*y/(1+x*x*y*y))*Math.Pow(x,Math.Abs(y))+
        Math.Pow(Math.Cos(Math.Atan(1/z)),2);
        Console.Write("v="+v);
        Console.ReadKey();

Error

Error CS7036 There is no argument given that corresponds to the required formal parameter 'y' of 'Math.Pow(double, double)'

Problem

You are calling Math.Pow() with just one parameter: Math.Sin(x + y) and it requires two parameters.

Solution

Check the formula and call the Math.Pow with two parameters, i.e.:

Math.Pow(Math.Sin(x + y), something_here )

Original answer (before OP added the code and error description)

I'm not sure what C7036 is but this snippet outputs 8:

        var x = 2;
        var y = 3;
        var number = Math.Pow(x, Math.Abs(y));
        Console.Write(number);

In this example x and y are ints and number is of type double.

Try to specify second parameter to your Pow:

Math.Pow(Math.Sin(x + y),SECOND)

in 

v = (1 + Math.Pow(Math.Sin(x + y))) / 
...
