good shit. its past midnight and i could still comprehend this on 2x. That means the video is good to understand while being effective.

Lol there is another test if your first one doesn't work for symmetry. For example while solving for x axis symmetry, if you substitute (r, -theta) and it doesn't work then you substitute (-r, pie - theta ). For y axis : ( r, pie - theta ) For origin : ( r, theta + pie ) You can't leave your answer as, "maybe".

Thank you man, you just saved half an hour of my life

You are an angel!! this is so clear and straightforward!!!

you are a math star!

Very clear explanation. Thank you so much.

How do you know if it is symmetrical or not?

thank you so much! This video was very helpful :)

Nice job!

the best way to test y symmetry is by substitute delta to pi-delta and

Very helpful Thanks c:

nice videos keep it up

Omg Gold bless you! you saved me from failing my math test please keep making more videos your videos were very clear and useful from other peoples videos. Thank you so much :)

Thank you....

Thank You :)

It doesn’t work when you have addition or subtraction

Thank you so much. ;UU;

Thhankkkyouuuuuu

I don't think that the word ( MAYBE ) helpful , there is no symmetry if we check the rules + simplify them more .. I meant rather that checking the symmetry about the y-axis by taking the negatives for r and theta , we can make theta = pie - theta , then by using angles identities we can see clearly is it equal our original equation or not , it is ?

it doesn't work for the equation r= -5-5cosϴ, it's supposed to be symmetrical to the x-axis but by replacing ϴ by -ϴ, it doesn't confirm that it's symmetrical to the x-axis even though it's supposed to be.

Eva PIERNAS cos(-theta) = cos(theta) so it would confirm symmetry

thanks a lot you are amazing ps: this is calculus 2 at AUS UNI
