They related the rate of change of these differences to a measure of urbanization at the urban station . The fact that an option 's delta ( the rate of change of an options price relative to the change in price in the underlying common ) is sloped is what allows one to profit from being short the stock without a corresponding decline in the option 's value offsetting the gain completely . Results are presented which shows that there is a correlation between the rate of change of cross-sectional area and the size of the leak . The rate of change of the temperature of the object is proportion to the difference between the temperature of the room and the temperature of the object . The derivative also measures the rate of change of the output of that function ( relative to change in the input ) near that particular input .
