Enter formulas for the three coordinates in terms of the parameters t and s. 

After you enter formulas tap the GRAPH ...

You can change the grid, opacity of a surface displayed, and rotate a surface.Exmp: 2*t^2+sin(s)-t/2

* : Multiplication

/ : Division

^ : Exponentiation

+ : Addition

- : Subtraction

Trigonometric & Inverse Trigonometric Functions:

sin( ) , cos( ) , tan( ) , asin( ) , acos( ) , atan( )

Exmp : tan(pi*t/3)+acos(s)

Use pi for the constant pi ; 3,14...
Use ln( ) for the natural logarithm, e for the natural base. 

Exmp : e^(2-s)*ln(t^2+1)

sqrt( ) for the square root abs( ) for the absolute value

max( , ) for the maximim of two entries

min( , ) for the minimum of two entriesfloor( ) , ceil( ) , round( ) for the previous, next, and the nearest integer ...
