    BAM again and again Mr Tarrou comes to the rescue. I'm coming back to this trig video and it just helped me solve a problem in Calculus 2 in the last section converting polar to rectangular BAM!

    WoooW...THANK YOU:) I really appreciate the offer to share my link with your son and your tutorees! My wife is currently researching other avenues and places to share my channel with....so help from subscribers like yourself is truly appreciated. We feel like everyone, everywhere should have access to FREE MATH HELP whenever they need it and have an easy way to find it.

    I have just started watching the video but man - the chalk hand-written title of the lecture is outstanding. It's the most beautiful piece of chalkboard content I so far have seen.

    Mr. Tarrou, I'm taking an online pre-calc class, and so now I have been calling you my teacher this whole semester. You have no idea what a difference finding your videos has made! You deserve a medal!

      ProfRobBob good flick, quick question.. How come the center is: (2,4) and not (-2,-4).. is it because you have to make -2 and -4 equal 0?

  • @georgesadler7830

    Mr Tarrou! Your whole channel has been my savior this semester. I'm nearing the end of my summer compacted college trig course, and my professor has been... well, less than stellar and the book isn't much help. Your videos have been so much help. I have recommended your channel to all of the students I'm in class with who're also struggling with the rapid pace of our course.
    I appreciate the fact that even though a lot of prerequisite knowledge on earlier material is required to do any given topic, you don't skimp on reminding viewers why certain functions, equations, etc. are the way they are. Your explanations that you give as you do these problems have been a tremendous help. Thanks again, and keep up the good work.

    • @profrobbob
      @profrobbob  10 років тому +1

      THANK YOU so much for watching, supporting, sharing my channel with your class, taking the time to comment and "thank the teacher" HollowPoint503 !
      It's always nice to hear that all this hard work is making a difference and helping so many students. I'm starting my 19th year of classroom high school teaching and still very much enjoy it but UA-cam has taken it to a whole new level of amazement...I still can't believe that I can teach students all over the world from my small home office in Florida! I never dreamed I would still be doing this 3 years and almost 500 videos later...but students like you continually reinforce why I do :) Keep spreading the word so I continue to groW and share my passion for math...BAM!!!

    Absolutely amazing! I had a similar idea like this. By covering a lot or all of the math section and providing those information to everyone, students may receive help at any given time. Keep up the good work. If you cover more sections, then you could potentially become the universal online math class.

      Our dream is to someday have an "M" next to my subscriber number:) I'm still teaching full time and trying to get my Calculus videos done. Then I plan to move on to completing my Algebra playlist. If some bank wants to sponsor my channel I could take time off and make videos full time! My wife and I just try our best to keep the dream alive every single day:) Thanks for taking time to comment and support my efforts.

    Sorry again about my first hasty answer that was incorrect. I will check another precalc book I have at school that hopefully will have a problem similar to yours. I hope the idea I had works but I am not positive. Your problem is harder than the ones I normally teach. Thanks for watching...

    My PreCalc book does not get real difficult into these kinds of questions, but I would think you would have to use a double angle identity to get rid of that number. Like sin2x is 2sinxcosx.

    Yes Amanda I look at demographics all the time, unfortunately the first time I saw your comment I was on my Ipad and Analytics were not loading. I wanted to look up some fresh stats for you and then forgot...so sorry for the long response time. I do have more female viewers in the US and Canada, but not be a big margin. There are many countries were my viewership is very dominated by males. The age groups are interesting as well...either fairly young or old with a dip in the 19's-30's

    Sir your handwriting is beautiful! Thank you for the math help!

  • @profrobbob
    @profrobbob  11 років тому

    Do you have an answer to check your work? You could multi both sides by r^2 giving you r*r^2=2rsinxrcosx. That would become (x^2+y^2)^(1/2)*(x^2+y^2)=2xy Then the left side could be (x^2+y^2)^(3/2)=2xy and then square both sides to have (x^2+y^2)^3=4x^2y^2.

    Word of advice: Wearing the checkered shirts like the one in this video causes a lot of aliasing in the video.
    Doesn't detract from the awesomeness that is this channel
