All you did wrong was to cancel 16/18 incorrectly. It is not equal to 4/3, but 8/9. And 8/9 times (3√3)/4 is (2√3)/3.Hello. I have a question, what do I do wrong that I cannot get the correct answer? My answer key says the answer is "(2√3)/3" and I got "√3". My solution and the question itself are attached below.
Oh, got it. Thank you! My carelessness is killing me ?All you did wrong was to cancel 16/18 incorrectly. It is not equal to 4/3, but 8/9. And 8/9 times (3√3)/4 is (2√3)/3.
Thanks you very much!All you did wrong was to cancel 16/18 incorrectly. It is not equal to 4/3, but 8/9. And 8/9 times (3√3)/4 is (2√3)/3.
Thank you very much!16/18<1 while 4/3>1. You need to learn to catch that error.
Thank you very much!I get \(y'=\dfrac{8x}{9(y-1)}\) so @\((3\sqrt{3},5)\) we have \(y'=\dfrac{24\sqrt{3}}{36}\).
i know the feeling.Oh, got it. Thank you! My carelessness is killing me ?
