hello friend
i want to make java program to slove trigomeric eq but i dont know how to stare as i m new in java i don't 9 how trigomeric eq can slove bye java can u tell me how i should thikg logicaly i need u r logical help so i can write my code with help that logic.

plz help me so that i can write code by myself.

Example 1: http://www.sosmath.com/algebra/solve...9/s91/img1.gif

There are an infinite number of solutions to this problem. To solve for x, you must first isolate the sine term.

http://www.sosmath.com/algebra/solve...9/s91/img2.gif

We know that the http://www.sosmath.com/algebra/solve...9/s91/img3.giftherefore http://www.sosmath.com/algebra/solve...9/s91/img4.gif The sine function is positive in quadrants I and II. The http://www.sosmath.com/algebra/solve...9/s91/img5.gifis also equal to http://www.sosmath.com/algebra/solve...9/s91/img6.gif Therefore, two of the solutions to the problem are http://www.sosmath.com/algebra/solve...9/s91/img7.gif and http://www.sosmath.com/algebra/solve...9/s91/img8.gif

The period of the sin http://www.sosmath.com/algebra/solve...9/s91/img9.gif function is http://www.sosmath.com/algebra/solve.../s91/img10.gif This means that the values will repeat every http://www.sosmath.com/algebra/solve.../s91/img11.gif radians in both directions. Therefore, the exact solutions are http://www.sosmath.com/algebra/solve.../s91/img12.gif and http://www.sosmath.com/algebra/solve.../s91/img13.gif where n is an integer. The approximate solutions are http://www.sosmath.com/algebra/solve.../s91/img14.gif and http://www.sosmath.com/algebra/solve.../s91/img15.gif where n is an integer.
note:this is one ex of trignometric eq.

You need to import the java math package, (import java.lang.Math)

use the method sin(). It takes doubles.

Eg.

 Java Syntax (Toggle Plain Text) 
double x = //something
double answer = sin(x);
answer = 2*answer - 1;
double x = //something
double answer = sin(x);
answer = 2*answer - 1;

All of the methods you need are in the Math Class.
