ReCalculate the X Y Coordinates of an Excel list according to a line angle. (VB.net, Excel Oledb or Interops)

Following steps are required. 1. Create a VB.net Solution and place a Picture box(640*480) and a Button named "Update" . 2. At the applicationstart draw a horozontal line from center of Picture Box at Zero Degrees. 3. Read the List of Points (X.Y) from an existing excel file. 4. Now allow the operator to rotate the line using mouse cursor... 5. After the software user has rotated the line at a certain angle He will click on button Update. 6. On sheet two of same excel paste new coordinates according to the new line angle. 7. Create a Two line chart in Excel Sheet 2 to demonstrate both sets of coordinates. (The new coordinates of the rotated point (x′,y′) are x′=xcos(θ)−ysin(θ) and y′=xsin(θ)+ycos(θ)
