Write a program that takes the x-y coordinates of a point in the Cartesian plan and print a message in a message dialog box telling either an axis in which the point lies or the quadrant in which it is found.

Sample line of output:

(-1.0, -2.5) is in quadrant III.

(0.0, 4.8) is on the y axis.



Task 3



Given: Sin(x) = x – x3 /3! + x5 /5! – x7 /7! + …

　　Cos(x) = 1 – x2 /2! + x4 /4! – x6 /6! + …



Write a Java program that does the following:



1.　　Reads a positive value x

2.　　Write two methods to compute sin(x) and cos(x) using the above formula. The summation in the loop above will stop (loop stops) whenever the value of the term becomes less than 0.0001.

3.　　Invoke the above methods and print either sin(x) or cos(x) depending on the user choice.
