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
