Math Handout The following lowercase Greek letters may be used in this course as variables or to represent constants. : Alpha : Delta (uppercase) : Lambda : Mu : Pi : Theta : Rho : Sigma : Tau : Omega (uppercase) The following symbols have special meanings and will be used on occasion in class. This symbol (an uppercase sigma) means “the sum of”. For example: ... 4 3 2 1 4 3 2 1 4 1 F F F F F i i i The first example would read, “The sum of i from i equals 1 to i equals 4, equals one plus two plus…” The second example would read, “The sum of all F’s equals…” This symbol means “is defined to be”. For example: F force m mass This symbol means “is approximately equal to”. For example: 3.14 3 2 0.67 This symbol means “change of”. Another way of defining it is as follows. Final Initial

UNIT I Table of Unit Conversions An equal sign (=) means that the values on either side are exactly the same. An approximately-equal sign ( ) means that the values on either side are within 1% of each other.
