The value of the cosine function is positive in the first and fourth quadrants (remember, for this diagram we are measuring the angle from the vertical axis), and it's negative in the 2nd and 3rd quadrants Now let's have a look at the graph of the simplest cosine curve, y = cos x (= 1 cos x) π 2π 1 1 x yExtended Keyboard Examples Upload Random Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals For math, science, nutrition, history, geography, engineering, mathematics, linguistics, sports, finance, music Graph as y = (2x)/(x4) by establishing a few data points with random values of x and noting the asymptotic limits at y=2 and x=1 The asymptotic limit x=1 should be obvious from the expression (since division by 0 is undefined) y=(2x)/(x1) is equivalent to y=2/(11/x) provided we ignore the special case x=0 As x rarr oo color(white)("XXXX")1/x rarr 0 and color(white)("XXXX")y=2/(11/x) rarr 2/1 = 2
