Operaciones en funciones. Las funciones con dominios que se traslapan pueden ser sumadas, restadas, multiplicadas y divididas. Si f ( x ) y g ( x ) son dos funciones, entonces para todas las x en el dominio de ambas funciones la suma, diferencia, producto y cociente están definidos como sigue. ( f + g ) ( x ) = f ( x ) + g ( x )The meaning is clearer if you introduce a function that only explicitly depends on the independent variables: g(x, z) = f(x, y(x, z)) g ( x, z) = f ( x, y ( x, z)). Then you mean ∂g ∂x ∂ g ∂ x, which is still a partial derivative (since z z is held constant), even though g g depends on x x in two different ways.

The tangent line is just the line itself. So f' would just be a horizontal line. For instance, if f (x) = 5x + 1, then the slope is just 5 everywhere, so f' (x) = 5. Then f'' (x) is the slope of a horizontal line--which is 0. So f'' (x) = 0.
