[TEX]sin(x) = x - x^3/3! + x^5/5! - x^7/7!...[/TEX]
In C++ terms :
//approximates in 3 expansions
float sinus(float x){
return x - (x*x*x)/(3*2*1) + (x*x*x*x*x)/(5*4*3*2*1);
}
Of course you can use a for loop and a factorial function and a power function to expand it more, but I'm not trying to give you the answer.
