Keep in mind that what you consider solid proof that the officer is lying may not appear that way to the judge. Even if your PD had done what you wanted him to do, the impact might have been much less dramatic than you believe. I see little point in making a complaint against your PD.
Algebra is a part of mathematics (often called math in the United States and maths in the United Kingdom ). It uses variables to represent a value that is not yet known. When an equals sign (=) is used, this is called an equation.
Calculus is the mathematical study of change, in the same way that geometry is the study of shape and algebra is the study of operations and their application to solving equations.
