  • Comment removed

  • I'm the 100th like :D And, I don't know what I would do without Khan Academy. Sal, you are the best at helping people get an intuitive understanding of even the toughest subjects!

  • ahh i get this...graphing it as a bound for a surface integral ... fu

  • @euch27 no because in polar coordinates there isn't negative radius

  • dude you just made this be so easy i was really confused till you came along

  • i just had to pause the video to let you know that you have the perfect anouncing voice.

  • What are you? The wisdom itself? lol

    Thanks!

  • @AmaymonF lol he has 3 degrees from MIT and one from Harvard

  • I am a little bit confused. You should have used the (180-150 = 30) angle because if you are going to use 150 then it will not shape the right triangle and hence you cannot use the previous defined rules which are for right triangle........... ???? Am I right...??

  • @ugerWadi

    If you use 30 degrees... you will not get the (-) that you need. Instead of being if the second quad... it will become the first quad or something like that...

    Of course, if you keep in mind of your location (2nd quad/ negative number), then you can use 30 degrees.

    Hope it helps

  • @Xclann Hmmm...yeah thanx man... :)

  • @patilnikh explain?

  • @patilnikh what IS revolutionary?

  • You also know that since 180-150=30, you have a 30-60-90 triangle and so the x coordinate is really -2sqrt(3)

  • this is easy as pi

    MR HAYWARDS SPECIALIST CLASS FTW

  • Nick Forse, Shut Up.
