PreCalculus - Polar Coordinates (15 of 35) Graphing Polar Equations: r=3cos3(theta), Roses

In this video I will graph polar equation r=3cos(theta), r=3cos3(theta), r=3cos5(theta), r=3cos7(theta), roses.

Next video in the polar coordinates series can be seen at:

Thanks Michael for your contribution. You are a professional instructor, detail oriented. You already draw everything on the board, so you do not waste time drawing. You get all the instructions delivered in a few again.

[manby]

thank youuu
my professor is really good at teaching but during this unit I was going through so much emotional stuff I couldnt pay attention, Im still recovering but my test is tomorrow! so i cannot thank you enough, i wish you can get profit out of these videos!

Thank you for sharing your knowledge and skills with us. I love your explanation, it's so easy to understand. My math teacher should watch your videos and learn how to teach.

[azoozfahol]

I respect you sir very much... you made this lesson so easy to me

[vanshbirju]

thanks really really helpful....appreciate your effort....

[sahriarsumaia]

May allah bless you sir, thanks from Bangladesh

[jianqinggao]

A very nice strategy mentioned in the video.

feels good to finally understand this 👌👌👌👌👌👌👌👌

thank you very much big THANK YOU clear explaination, btw anyone 2024?

hi i am just wondering does it mean for r=acos3theata it would be 360/3 to find location of first petal and a petal every 120 degrees whilst for r=asin3theata it would be 90/3 to find the location of first petal and then 360/3 that theres a petal every 120 degree? thank you so much these videos are so helpful

[jarelmontes]

On the last one, where did that 13 degrees come from ??

[michelef]

You did a really good job explaining the pattern, but there's something about the frame of reference that is messing me up badly.
At 5:10 you can see that for teta = 120 the value of r is equal to -3. How can we say that a radius in the top left quadrant is negative? Which is the convention underpinning a polar plane graph?

[Itaaugusto]

Nossa adorei sua explicação. vc é muito bom, parabens

[TacTzGaming]

360 degrees and 0 degrees do not equal each other (aren't the same angle) they have the same terminal point

[shikhargupta]

Why do my Math and Physics teacher make me watch the same guys videos 😂

[Bearfair]

what determines the width of the leaves?? and thank you for your lectures

[ntsikammiwa]

thank you do much, this was so confusing

[fantasiworld]

Sir what is the difference between rose 1 or rose 2

[siphilipe]

Few tutors say why? ex:(51.4/4), and (72/2) and briefly respond because..., Additionally, it looks like "draw that rose BUT without lifting a marker." LOL

My professor is a young kind of atractive woman but only if she taught like you. I would choose you over her.
