Question Type : C++ expressions -----------------------------------------------------------

Given the following equation, complete the function getFXY to return a correct value of fxy given the values x and y. ________________________________________ | - - - - | | 2x-1 | | PI | fxy = | 2 sin | ---- | + 0.5 cos | ----- | \ | | PI | | y-1 | \| - - - -

The sample runs are as follows.

Sample Run 1:

Enter a value for x and y: 3.5 6.7 3.50:6.70 fxy = 1.51

Sample Run 2:

Enter a value for x and y: 10 20 10.00:20.00 fxy = 0.17

Sample Run 3:

Enter a value for x and y: 5.5 7.4 5.50:7.40 fxy = 0.59 */
