Csc Graph Points. Plot any two reference points and draw the graph through these points. Similarly when θ 270 sinθ 1 and hence cosecθ 1 as well.
Both y csct y csc t and y sint y sin t are shown in Figure 1669. 1 sec cos yx x and 1 csc sin yx x This means the yvalues on the graphs of secant are the reciprocals of the y values on the graph of cosine same for cosecant and sine. The vertical asymptotes on the csc graph are at xpi k.
To graph a cosecant function we start with the sine graph by first determining the amplitude the maximum point on t.
These observations enable us to plot two points on the graph of cosecθ. The graph of cosecθ can be deduced from the graph of sinθ because cosecθ 1 sinθ. This is half of the period. Both y csct y csc t and y sint y sin t are shown in Figure 1669.
