# How do you find the period of #y=cot(x-π/2)#?

##### 1 Answer

The period of the ratio functions are

#### Explanation:

The period of

In trig, we have the form

a = Amplitude. In terms of sin/cos, this is what affects the cusps of the graph. for

b = Periodicity. This is the part that you're looking for. Because this value is 1, the periodicity is unchanged. We can find the period of any trig function by feeding some information into the following equation.

Period =

c = Horizontal Shift. In your example this graph will be shifted

d = Vertical Shift. This value will shift the graph up or down to the value of d.
