Study Notes
Derivatives in Calculus
- The derivative of the position of a moving object with respect to time represents the velocity of the object.
Derivatives in Functions
- The derivative of a function of a single variable at a chosen input value represents the rate of change of the function with respect to the input at that point.
Geometric Interpretation
- The derivative is often described as the slope of the tangent line to the graph of the function at a given point due to its connection with the tangent line.
Multivariable Functions
- In the generalization of derivatives to functions of several real variables, the derivative is reinterpreted as a linear transformation or a matrix of partial derivatives.
Dependent and Independent Variables
- The derivative measures the rate of change of the dependent variable with respect to the independent variable.
Derivatives in Finance
-
A common purpose for using derivatives in finance is to hedge or mitigate risk.
-
Most derivatives are traded over-the-counter (OTC) rather than on an exchange.
-
A common example of a derivative is an option.
-
Since the financial crisis of 2007-2009, there has been a trend in the United States towards increased regulation and central clearing of derivatives.
-
A derivative derives its value from an underlying entity, such as an asset, commodity, or currency.
