Question

The period of y = 2cotx is _____.


π/2
π
2π <---
4π

Answer 1

so period = ?

Answer 2

\[f(x+T)=f(x) \rightarrow T = period\]
\[2\cot(x+T)=2\cot(x) \rightarrow x+T=x+ k \pi so T=k \pi , the original period is when k=1\]

Answer 3

@amoodarya then it would be 2pi/1? equals to 2pi?

Answer 4

x+T=x+k pi
T=k pi
k=1 for original period
so T=pi

Answer 5

the period is pi?
