There are similarities in both categorical and quantitative data that are worth getting to know. Categorical variables are those that provide groupings that may have no logical order, or a logical order with inconsistent differences between groups (e.g., the difference between 1st place and 2 second place in a race is not equivalent to the difference between 3rd place and 4th place). For example, a home thermostat provides you with data about the changing temperatures of your home on a paired device. If C is a closed curve that is the boundary of a surface S, and f and g are C2C^{2}C2 functions, show that (a) Cfgds=S(fg)dS\int_{C} f \nabla g \cdot d \mathbf{s}=\iint_{S}(\nabla f \times \nabla g) \cdot d \mathbf{S}Cfgds=S(fg)dS (b) C(fg+gf)ds=0.\int_{C}(f \nabla g+g \nabla f) \cdot d \mathbf{s}=0.C(fg+gf)ds=0.
