Code:
import java.math.*;
class Stuff{
public static void main(String[] args) {
int var4;  
var4 *= (3.14/180); // convert from degrees to radians;
  double sin_var4;
  for (int j = 5; j <= 10; j++){
	sin_var4 += Math.pow(var4,j);
  }
System.out.println(sin_var4);
}}

Doesn't work... sigh always says sin_var4 0.

For those of you who might ask what sin_var4 is... (or what I am trying to do).

I am trying to write the defination of Sine function, which in Maclaurin series is x - x^3/3! + x^5/5! - ... x^n/n! + x^n/n! ... etc

and also seems like the compiler says sin_var4 is undefined.. why??
