Question: having trouble plotting an equation in 3D

Hey Everyone,

I'm a Calculus III student and first let me say i love maple because it really helps to visualize things, however, i'm having trouble plotting an equation.  I'm doing a 2nd degree taylor function for sin(x*y) which is:

z = 1 - (pi/8)(x-1)-(pi/2)(x-1)(y-(pi/2))-(1/2)(y-(pi/2))

And it says that it cannot plot the equation.


I've also noticed that the plot of sin(x*y) is different from the plot of sin(x(y)).
