Definition of Function A function from one set X to another set Y is a rule that assigns each element in X to one element in Y. 4.1.1 Notation If f denotes a function from X to Y‚ we write 4.1.2 Domain and range X is known as the domain of f and Y the range of f. (Note that domain and range are sets.) 4.1.3 Object and image If and ‚ then x and y are known respectively as the objects and images of f. We can write ‚ ‚ . We can represent a function in its general form‚ that is

Trigonometric Functions The properties of the 6 trigonometric functions: sin (x)‚ cos (x)‚ tan(x)‚ cot (x)‚ sec (x) and csc (x)are discussed. These include the graph‚ domain‚ range‚ asymptotes (if any)‚ symmetry‚ x and y intercepts and maximum and minimum points. Sine Function: f(x) = sin (x) * Graph * Domain: all real numbers * Range: [-1 ‚ 1] * Period = 2pi * x-intercepts: x = k pi ‚ where k is an integer. * y-intercepts: y = 0 * Maximum points: (pi/2 + 2 k pi ‚ 1) ‚ where

Dependent Variable - The output variable of a function; the variable whose value depends on the input‚ or independent variable. Domain - The set of all inputs for which a function or relation is defined. Even Function - A function f is even if f (x) = f (- x) . Function - A relation which assigns exactly one element in its range for each element in its domain. Horizontal Line Test - The test by which it is shown whether a function is a one-to-one function or not‚ and therefore whether
