CHECK MY ANSWER? Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = -5 - 5 cos θ I got y-axis.

there is no graph with the problem. i plugged it into wolfram alpha

I don't really like how wolfram alpha sets up their graphs and how there's no customization The online grapher "fooplot" is a better choice for polar plots http://fooplot.com/plot/dreqosz0s8

Well that looks completely different from the wolfram alpha one!

From wolfram I got that the graph was symmetric along the y axis and with this one im getting its symmetric along the x axis..

what did you type into wolfram alpha?

-5 - 5 cos θ

I see. It's thinking you want to graph y = -5-5*cos(x) on the regular cartesian xy coordinate system (not the polar coordinate system)
jim_thompson5910
  • jim_thompson5910
if you type in "-5 - 5 cos θ polar", that key term "polar" at the end, you get a polar graph

Oh, alright, I see...

fooplot is still a better choice though because you can move the graph around, zoom in/out, etc

So it seems my graph will be symmetrical along the x axis after all
jim_thompson5910

correct
