java.util.UnknownFormatConversionException error

Why do I get this error?

Code:

---


Exception in thread "main" java.util.UnknownFormatConversionException: Conversio

All I want to do is convert a number from degrees to radians (Math.toRadians())and find the Math.sin and Math.cos of it

Invalid conversion in your code. Double check it. Can you show your conversion here to see.

Can you show the printf at line 55?

Heres the snippet of the code that asks to print:

Code:

---

public static void main(String[] args)
        {
                double x;
                x = (Math.PI)/4;
                double  rad=0;
                double result=0;
                System.out.printf("Evaluate x = %1.0f",x);
                result = sine_evaluate(x);
                System.out.printf("%nSin Result = %5.15f",result);
                result = cos_evaluate(x);
                System.out.printf("%nCos Result = %5.15f%n",result);
                rad=Math.toRadians(x);
                result = Math.sin(rad);
              System.out.printf("%nActual Sine Result = %5.15f%n",result);
              result = Math.cos(rad);
              System.out.printf("%nActual Cos Result = %5.15f%n",result);
           
        }

I see more than one printf.
Which one is causing the error?

The errors are coming from the last 4 lines.The rest of the functions are getting executed. Im getting results if I dont include the last 4 lines.

Can you post THE LINE that causes the error?
With the error message.

Have you tried debugging your code? Try printing the values WITHOUT formatting.
Can the value of result be NaN?

And what's the data type of variable result. I cannot find there declaration in your code segment.
