	number of points describes the number of grid points for both variables. The default is 25.
	Start specifies the start points of both variables, that is, an array of length 2. The default values are (0, 0).
	End specifies the end points of both variables, that is, an array of length 2. The default values are (1, 1).
	Formulas is an array of three strings describing the three functions. Each of the functions represents a component of the surface under investigation. The formulas can contain any number of valid variables.
	Variables is an array of two strings representing the two variables with respect to the naming conventions of the Formula Parsing VIs. The default variables are (t1, t2).
	X is the array of the x values at the grid points defined by the parameters.
	Y is the array of the y values at the grid points defined by the parameters.
	Z is the array of the z values at the grid points defined by the parameters.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.
	ticks is the time effort for the whole calculation of the function values in milliseconds.

Eval X-Y-Z(t1,t2) Details

The following equations describe a part of the unit sphere in 3D:

x(t1, t2) = sin(t1)

y(t1, t2) = cos(t1)sin(t2)

z(t1, t2) = cos(t1)cos(t2)

In the Formulas control, only the right hand side of the previous three equations needs to be entered.
