What is "pai"? Is this meant to indicate [imath]\pi[/imath], or something else?Find all x,y points on the graph if r*cos(p)<=2 and -pai<=p<=pai

Does [imath]r\cdot \cos(p)[/imath] indicate a polar-coordinate expression?

Are you sure that this equality is the equivalent to the original INequality?I need to figure out why the answer to this question is (x-1)^2+y^2=1

What have you tried, working with the above information?Just to remind people here:

tan(p)=y/x

cos(p)=y/r

r^2=x^2+y^2

Please be complete. Thank you!

Did you mean "Cos(p)=y/r

Describe the graph you would get, if you plotted the equation above.(x-1)^2+y^2=1
