I am taking an online pre-calculus class where the professor is not lecturing, but asks us to teach ourselves from the text. It is nearly impossible. I started watching your videos before reading each section in the text - what a tremendous help. Thank you for supplementing this class without even realizing it!! You are very thorough and articulate - easy to understand.
You're welcome Jenny...glad to hear that you are finding them so helpful! If you have anyway to contact the promoters of online class maybe you could share my channel and your experience with them...and if you can, please remind everyone to subscribe to support these free educational channels...THANKS in advance for your help in helping us groW!
You're my hero. You've not only saved my GPA but allowed me to continue on my desired path to an Engineering degree. So again THANK YOU!!! and keep it up!
There needs to be more math teachers such as yourself. You know the information well and have a great/positive attitude in the way you convey the information. Thank you so much.

My son, who is in middle school, is taking precalculus at the local high school and because of a non-optional middle school orchestra field trip, he missed the class in which the teacher introduced this topic. When he returned the next day, he asked the teacher if she could direct him to some notes or something that would help him learn what he missed. Her response: “Too bad. You picked a bad class to miss. Good luck catching up!” Thank goodness for UA-cam and your outstanding videos! He just watched this one. His reaction: “I sure wish this guy was my teacher!” 🙂
THANK YOU @Josh Kershenbaum for taking the time to share your appreciation and experience with us and most of all for bring an involved parent! Sorry for your sons bad experience but it lead you here and I have over 600 videos so hopefully he will find this channel helpful for future classes too! I can at least be his UA-cam teacher...BAM!!! Please share this free resource with other parents and maybe his teacher too, so ALL current and future students can use this free resource. Please remind them how important it is to like, subscribe, support the ads and keep spreading the word about these free educational channels you find helpful...that's how we grow and remain free for everyone:D
@The1AndOnlyKerrySue If you knew how many times that day I made those kind of silly little mistakes...it was a very off day! So, I am glad this was not another example of my mind and words not in agreement. Thanks anyway...and thanks for watching:)

You are so SO welcome and I love hearing that you're grades are improving too! THANK YOU for choosing my videos to learn from and I hope you will share my channel info with others in my quest to help me groW!
Professor RobBob, thank you for a great introduction to Parametric Equations. Parametric equations are useful in Calculus Two, Three, Physics plus other Advanced classes in Mathematics. Parametric equations improve my graphing and analytical skills in Mathematics. All four examples shows the basic concepts of Parametric Equations. This is an error free video/lecture on UA-cam.
I am going to reference another teacher because I only do a little with parametric equations. Horizontal asymptotes are when x approaches +- infinity. To find out what happens as x-> infinity, solve for t: (ex) x=1/(t-1) >>> t-1=1/x>>>> t=1/x+1. Now take the limit as x-> infinity. T=1 and you have the horizontal asymptote. Do the same for y for the vertical asymptote.
And THANK YOU for supporting by choosing my channel, liking and subscribing! I hope to continue to be your go-to UA-cam math teacher...and please tell your friends where to find me too:D
I do have a trophy that claims I'm an "Everyday Hero" but hearing it from a viewer certainly is nice! That's awesome that you're grades will remain high enough for you to continue to pursue your desired path in engineering! Here's a little quote for you to refer to as you move forward: You have all the reason in the world to achieve your grandest dreams. Imagination plus motivation equals realization. Thanks for watching and best of luck to you Kyle!
Thanks for the testimonial comment Stefano:) Thank you too for supporting by liking and subscribing...I do love teaching and UA-cam has certainly taken that love to a whole new level, thanks to satisfied students like you!

hi, prof rob, its Ay I need you help. find the parameterization for the ellipse given by the equation x^(2)/9 + y^(2)/64 thst starts from the point (-3,0) and travels counterclockwise exactly one full time to end at (-3,0) again. my 1st questtion is how do i know how to pick my range of values? , In class my teacher used (pi, 3pi) also how do i know which function x or y should be. my teacher used x= 3cos(t) and y= 8sin(t)
I don't think I am going to be a huge help here because my book does not do any of these problems backwards like this and I don't want to tell you anything wrong. On a unit circle, cosine is the x coordinate and I see how the square root of nine from under the x is the coefficient of cosine. You can see the same pattern with y and sine being y on the unit circle. Also if you set 3 cos(t) = -3 you will get the answer of pi.
No I'm not related but I've seen his videos:) I wish I had the subscriber count he did...lol Thanks for watching and don't forget to sub and keep sharing all the free channels that you enjoy...BAM!!!
(-2)^2 and -2^2 both equal 4. I think you meant that -2^2 and -(2)^2 are different because -(2)^2=-4. (with the negative on the outside of the parentheses.)
How do get an e-mail to you to request certain types of problems to be worked out by you? I have some questions about more specific types of parametric equations. Specifically, finding parametric equations for an object in motion and not just for circles.
In the high school classes I teach we only touch on the very basics of parametric equations so I am probably not your best source for help on this type of question, sorry.
Just a friendly observation. I hear you say "regular function notation" when you refer to eliminating the parameter. Parametric equations often produce plane curves which are NOT functions, like ellipses for example. By definition only the x(t) , y(t) are assumed to be functions.
t is time, so the first value of 1 you use is the first point the next t the second and so forth. This is what determines the direction the arrows should be.
Hi ..how do you find the t values when the time interval is between 0 and pi ... I watched ur video n read books but yet iam not getting it ..I have a test the day after tomorrow n really need to know..plz reply ...I would be blessed so do u.....
+Kelbi Bieber that's teamwork..."you" take the time to study and "I" supply the study help...BAM!!!

Can you help me to solve this simple question, please? Determine the parametric form r(t) of the closed curve going from the origin A(O, 0) along two straight lines to B(l, 2) and D(2, 4), and returning from D(2, 4) return to the origin along y = -(x - 2)^2 + 4.
Vignesh SR I am very sorry. With my full time job and now trying to Close Caption the videos I have made so far I am running out or time to answer math questions. If this problem is from a textbook you can check out Slader dot com where you can find student/teacher generated solutions. I hope you find the solution you desire. Sorry I could be more helpful.
+Love Patel It doesn't really matter since cos/sin functions restrict the values from going higher or lower infinitely. They just make the values bounce up and down the min and max values for that function, otherwise known as amplitude. So if you were to make a T-table to calculate all times of 't' infinitely, you would get a graph with a curve that repeats itself indefinitely, looking like consistent wavy snake basically c: Edit: Oh right you wanted to specifically know what you're meant to graph if no range is given. Well I suggest to do 2pi or 360 degrees as your range, basically just one or two periods worth of your function. It repeats after one period anyway, that's a given. For functions that aren't cos/sin, I'd suggest to just graph as many points as needed to see a general trend before it becomes obvious enough of what value is likely to come next.

How are we supposed to make the T-table if the range of time 't' is not given ? Does it mean its ( -ve infinity to +ve infinity) by default?
+Love Patel It doesn't really matter since cos/sin functions restrict the values from going higher or lower infinitely. They just make the values bounce up and down the min and max values for that function, otherwise known as amplitude. So if you were to make a T-table to calculate all times of 't' infinitely, you would get a graph with a curve that repeats itself indefinitely, looking like consistent wavy snake basically c:
Edit: Oh right you wanted to specifically know what you're meant to graph if no range is given. Well I suggest to do 2pi or 360 degrees as your range, basically just one or two periods worth of your function. It repeats after one period anyway, that's a given. For functions that aren't cos/sin, I'd suggest to just graph as many points as needed to see a general trend before it becomes obvious enough of what value is likely to come next.

Your shirt offends me, professor. I like when you care. :(
No offence intended Impuhlz because the truth is that I ALWAYS CARE!!!
Occasionally I have to wear these shirts in class because some of those students are not always as appreciative as my UA-cam students:(
Yeah cuz they don't know how lucky they are to have you as a teacher
niceness :p
