    1. The problem statement, all variables and given/known data
    3a) Find the equation of the tangent plane to the function f(x,y) = sin(x)cos(y) at the point (∏/3,∏/2).


    3. The attempt at a solution

    There is quite clearly a z in the definition. What's going on?

    It's the way you have g defined. According to the function definition, g := z - sin (x)*cos (y), so you need 3 arguments to specify a value for g.

    So if I evaluate the function f(x,y) = sin(x)cos(y) at the point (∏/3,∏/2) and then use that point to find my value of Z it should work?
