PLEASE HELP!!! TRYING TO GET THIS DONE & I DONT UNDERSTAND

write a number of C++ functions, and a test driver ( harness ) to test them with.

double distanceAndVector( double x1, double y1, double x2, double y2, double & deltaX, double &deltaY );

--Returns the distance between ( x1, y1 ) and ( x2, y2 ).

--Stores in ( deltaX, deltaY ) the vector pointing from ( x1, y1 ) to ( x2, y2 ).

int xCosXySinY( int nRows, int nCols, double x[ ], double y[ ], double result[ ][ MAXCOLS ] );

--Fills in result[ ][ ] by calling double xCosXySinY( double x, double y );

--The array passed to result must have MAXCOLS columns.

--nRows and nCols should be the number of rows and columns of result to fill. They should be checked for validity.

--x[ ] holds the X values to be used for each row.

-- y[ ] holds the Y values to be used for each column.
