Trig. Graphs!!

Study for Trig. Graphs:

Sec Graph!!


A graph of sec(x). sec(x) is defined as 1/cos (x)

Cos Graph!!


A graph of csc(x). csc(x) is defined as 1/ sin(x)

Sine Graph!!


Careful analysis of this graph will show that the graph corresponds to the unit circle. X is essentially the degree measure(in radians), while Y is the value of the sine function.

Cos Graph!!


As with the sine function, analysis of the cosine function will show that the graph corresponds to the unit circle. One of the most important differences between the sine and cosine functions is that sine is an odd function while cosine is an even function.

Sine and cosine are periodic functions; that is, the above is repeated for preceding and following intervals with length 2π.

Cot Graph!!


A graph of cot(x). cot(x) is defined as 1/tan (x) or cos(x)/sin(x)

Tan graph!!


A graph of tan(x). tan(x) is defined as sin (x)/cos (x)
