JAVA EXERCISE OPERATORS

SAMPLE: Writing a program to input 2 triangle edge and the angle between those ones, then compute and display the area of that triangle.

Formula:

Solution :

Open NetBean, create a new project, names Project, then chose Finish.

Input the name of the Project is BaitapB2

In Project window, right click to the package baitapb2, choose New/Java Class..

Type name of new class at Class Name and choose Finish to create class.

Name of this class: BaitapDemo

Type code to input 2 edge, and angle then compute the triangle area as follows:

To run class BaitapDemo, open class BaitapB2, create an instance of class BaitapDemo and click on Run icon or press F6.

Exercises: From the sample exercise, do follows exercises:

1: Compute n^th root of x, knowing

. Input values of x and n from keyboard.

2: Write a program to compute the area of a triangle

Applying the formula:

with

 when a, b, c are 3 edges of a triangle and are input from keyboard.

3: Write a program to compute the distance between a point I(x0, y0) 

To a line which has equation  D: Ax + By + C = 0. 

Require: Input values of x0, y0, A, B, C from keyboard.

Suggest: Formula to compute the distance
