CH 330 Lecture 2: L1_-_Periodic_Function_Graph_of_Sine_Cosine_FILLED
Document Summary
A function is said to be periodic if it repeats itself at regular intervals. Some important terminology related to periodic functions is listed below. Maximum value: greatest value reached by variable on the vertical axis (the y-axis). Minimum value: smallest value reached by variable on the vertical axis (the y-axis). Midline: horizontal line that divides the graph in half vertically. Amplitude: half the difference between the maximum and minimum values. This is the distance from the midline to the maximum/minimum point on the graph. Period: graphically, it is the horizontal distance covered during one complete cycle (peak to peak, or valley to valley). Generally, the period represents the length of time it takes before a periodic relationship repeats itself. Complete the following table and plot the ordered pairs (x, sin(x)). y y = sin(x) x. Complete the following table and plot the ordered pairs (x, cos(x)). y y = cos(x) x.
