I want to develop a console application that can calculate the range of a missile. The application asks the user to enter the height of the missile trajectory (suppose H). Once user enters the height, the application then asks the user to enter angle of attack (suppose Theta). The application then calculates the range according to the following formula: using C#

Range= 4*H/tan(theta)
 where      
tan(theta) = sine(theta)/cos(theta)

this is my code:

C#

using System;


namespace Mid2
{
    class Program
    {
        static void Main(string[] args)
        {
            float tan * theta = sin(theta) / Cos(theta);
            Console.WriteLine("Enter the height: ");
            float H = float.Parse(Console.ReadLine());

            Console.WriteLine("Enter the angle: ");
            float theta = float.Parse(Console.ReadLine());

            float Range = 4 * H / Math.tan(theta);
            Console.Write("Result = {0} " +Range);

        }
    }
}

Seems to me you are missing the important "range" factor of the energy/momentum imparted to the missile by its propulsion system.

what do you mean with your first line:

float tan * theta = sin(theta) / Cos(theta);

perhaps something like this ?

Func<double, double> tan = x => Math.Sin(x) / Math.Cos(x)

I would change your code snippet to:

C#

void Main()
{
    Func<double, double> tan = x => Math.Sin(x) / Math.Cos(x);
    Console.WriteLine("Enter the height: ");
    double H = double.Parse(Console.ReadLine());
    Console.WriteLine("Enter the angle: ");
    double theta = double.Parse(Console.ReadLine());

    double Range = 4 * H / tan(theta);
    Console.Write("Result = {0} " ,Range);
}

As Math.Sin() returns a double you might want to change your local variables to the same type.
