Trigonometric Functions and its Testing by Group 6.

Trigonometric Functions such as sin, cos and tan are implemented by using taylor serise and tested using JUnit in this project.

Functions Included

1. sin function
2. cos function
3. tan function

Test Cases

1. Calculating accurate value in radian
2. Checking other functionalities such as Power and Factorial
3. Calculating accurate value in degree
4. Normalizing radian value between 0 to 2 pi.

Description of Test Cases

Test Case 1:

1. Checking accuracy of Trigonometric Functions

• First test case is to check whether the value which is generated by sin, cos and tan is accurate or not.

Test Case 2:

2. Checking other functionalities

• Second Test case is used for checking other supporting functionalities such as Power and Factorial which are cruial to count term in taylor serise.

Test Case 3:

3. Checking accuracy of Trigonometric Fucntions in Degree

• Third Test case is used for whether the functions are converting degree inputs to trigonometric values. For, that We converted degree to radian value.

Test Case 4:

4. Normalizing radian value between 0 to 2 pi.

• Forth Test case is used for normalizing any value to 0 to 2 pi. ex. 60 radian.
