Sinx

[mia023]

i was wondering if i could compute sin x using Taylor series my code was as follows i guess it is not correct. Tell me please what is wrong and what i should do. I guess there are alot of errors in the code(logical... )

[CODE=java]public class Sin{
public static void main(String []args){
double x=Double.parseD ouble(args[0]);
int stop=25;
int n=0,product=1;
double sum=0.0;
double sign=Math.pow(-1,n+1);
for(int i=1;i<stop;i=i= i+2){
sum+=sign*Math. pow(x,i);
}
for(int i=1;i<stop;i=i+ 2){
product*=i;
int frac=(int)(sum/product);


}
System.out.prin t(frac);
}
}[/CODE]

Apparently you did not read my previous message, since you responded again (twice) without using code tags and repeating your original statement. You do not need to post the same thing over and over to get a response. You do need to post your code using CODE tags. Do not make me warn you again because that will be the third time.

@OP: can you write down the first few terms of the Maclaurin series for us? You
want the Taylor series with a derivative w.r.t. x at x == 0. Just the mathematical
formula, no Java source code is needed.

kind regards,
