Question

How do you graph `y=cot(x/3+240)`?

Answer 1

See graph and explanation.

Explanation:

The plot is for y against x in radian.

If it is `240^o = (4/3)pi` radian, the befitting equation is

`y = cot ( 1/3(x+4pi))`
The period = `pi/(1/3) = 3pi = 9.425`, nearly.

The Socratic graph is immediate.
