PreCalculus - Polar Coordinates (16 of 35) Graphing Polar Equations: r=3sin3(theta), Roses

[@mundsri4955]

My professor makes it too complex 🤯 thank you so much for this!

[@HammadKhan-xu7lc]

Sir, you're a life saver. My prof made this so hard.!! Respect.

[@MichelvanBiezen]

Glad you found our videos! 🙂

[@peacepeace5788]

This’s the shortest method I love it

[@MichelvanBiezen]

Glad it was helpful!

[@ニーア-g8h]

If you're working in radians an easier way (in my opinion) to find the first leaf is by taking the equation 3sin(k*theta), remove the 3, and set the rest of the equation equal to 1. You can take the inverse of 1 to get pi/2 and then divide the k value to get the angle where the first leaf is. also by 'easy' I mean that in retrospect as to why he randomly gets 90 degrees and divides the k value. this method makes sense to me personally because I can see where the numbers come from. works for degrees too in case you're wondering.

Shush u nerd 🤡

[@ddee_6234]

thank you sir. I was really confused in my maths class but thanks to you, I can relieve now.

[@MichelvanBiezen]

You're welcome!

[@ronycb7168]

Technically one should start from the the pole because sin 0 is 0, otherwise awesome video and I found this very helpful because I was looking for an easy way to sketch these polar curves.. Thanks!!

[@MichelvanBiezen]

Glad it helped!

Wow Thank you so much, it's so simple

You are welcome. Glad you liked it.

[@AbdulwahidBwanali]

This is awesome, i like it and very easy to apply

[@tanvirhossainpretom547]

thank u sir. I am from Bangladesh. I like your system really

[@mn-yv2ur]

Thank you so much for the great explanation.

[@FateOfPraedyth]

Wait I was supposed to learn this in PRE CALCULUS? I'm in Cal 2 and a couple days ago was the first time I've seen these.

[@MichelvanBiezen]

Yes, we don't learn everything we need to in our classes.

[@FateOfPraedyth]

@@MichelvanBiezen Okay good, I thought I was majorly behind on that 😊. Thank you!

[@sciencematters1614]

How do you know how wide to make the leaves?

[@kingsleymbre9195]

This explains a lot to me

[@a4onnr]

Thanks sir Can you please explain the maths behind dividing 90 by the coefficient of theta for first leaf

[@MichelvanBiezen]

It is done through observation rather than a mathematical formula. As you begin to graph the various functions by plugging in values, you will observe this relationship.

[@a4onnr]

@@MichelvanBiezen understood thanks

[@numan3795]

MashaAllah amazing

[@MichelvanBiezen]

Glad you liked the video

[@durgamgr4354]

Great explanation.

[@AD-wg8ik]

Precalc? I didn't learn this until Calc II

[@smc9901]

Excellent work

[@muzamil1069]

Just mind blowing

[@kaiokenkamehamewave]

Awesome to be learning Math with Master Yoda on a white horse

[@MichelvanBiezen]

We'll have to get a white horse. :)

Thank you proffesor

[@vikashkushwaha3512]

Excellent explanation

[@kazmtuwileb6837]

hello it is not necessary to make table correct ?

[@MichelvanBiezen]

Sorry, I didn't understand your question.

[@kazmtuwileb6837]

@@MichelvanBiezen I mean no need to make table for graphing this polar ? table by ( r ) and (theta) value I mean.

[@owenpalmer1018]

who writes the trig functions in cursive?

[@MichelvanBiezen]

An old habit.

[@طهالشويلي-ج3ص]

😀😀😀thank you......your student

[@anmolanmol1099]

best explaination sir

[@mahmoudsobih1740]

can you do cousres hwo to became legend like Michel van Biezen?

[@MichelvanBiezen]

There is no secret. To accomplish anything in this world you must have a passion for it and then you must work very hard for many hours. Without the passion it is difficult to keep up the effort for as long as it takes. My passion has always been teaching. It is the hard work of my wife behind the scenes that has made it possible for us to make these videos. 🙂

[@mahmoudsobih1740]

​@@MichelvanBiezen I really love math and physics and I want to enter mechanical eng and be a big dr. you are really easy in explaining examples and solution , I'm glad to see your videos

[@MichelvanBiezen]

Follow your passion and don't be concerned about becoming a "big person". We are not in control of our future, but we can enjoy our path to the unknown. 🙂

[@yunachoi8465]

Do you always start with 90 degrees? Or does that have something to do with the 3 before the sin?

[@yunachoi8465]

never mind haha i didn't watch the full video

[@themishra6853]

Nice explain sir

[@themishra6853]

If any method for r=1+cos (theta)

[@themishra6853]

?

[@MichelvanBiezen]

Use a table of values. Calculate r for various values of theta.

[@ramatallynadeem8750]

eg.3sin3♧ has 6 leaves or 3 leaves ???

[@MichelvanBiezen]

Only 3 leaves. For the angles from 180 degrees to 360 degrees, the curve traces over the graph made when the angles are chosen from 0 degrees to 180 degrees.

[@KuldeepSingh-wo4yl]

Cool👍👍👍👍

[@luismartinez5598]

Why are these people not teaching at schools? Ah that's right, they can't afford them.
