Approximation.NET - An implementation of approximations to common trigonometric functions

Features

• Sine and cosine approximations using polynominals with both low and high precisions.
• Sine approximation using Taylor series
• Fast inverse square root (1/sqrt()) function using smart bitshifting
• All written in C#

Examples

static void Main(string[] args)
{
	float realInvSqrt = (float)(1 / Math.Sqrt(5));
	float approxInvSqrt = Approximation.InvSqrt(5);

	Console.WriteLine("Real: " + realInvSqrt);
	Console.WriteLine("Approximated: " + approxInvSqrt);
}

Output:

Real: 0.4472136
Approximated: 0.447141
