Unformatted text preview: value to the ﬁrst key point, and so on, until we get the x-coordinates of the 5 key points: c ω , c ω + T 4 , c ω + 2 T 4 , c ω + 3 T 4 , c ω + 4 T 4 5. Find the corresponding y-coordinates of the 5 key points. 6. Plot the 5 key points and ﬁll in one period (one cycle) of the graph. 7. Complete the graph by repeating the cycle in either direction. 1...
