    dy/y^2 can be rewritten as (1/y^2)dy and then as y^-2*dy. So integrate y^-2*dy and you have -y^-1 or -1/y

    Great! Best of luck with the AP exam. The phrasing of these questions can vary a bit as it depends on an author's writing style.

    Does the ivp has two solutions or infinitely many solutions?
    Please reply

      John Martinez It's the inverse rule. He took the inverse of (-1/y) which is basically (1/-1/y) which you just swap the top and bottom and that becomes just -y then he had a do the exact same thing to the other side and multiply both sides my negative one to have it y= instead of -y=

    • @archib0ld1

      +John Martinez
      All he did was multiply "y" to both sides and then divided (x+(1/3)x^3+c) on both sides.

      Basically, if you have something on the denominator on one side and move it to the other side it will be in the numerator position. That leaves you with 1/y is equal to whatever. Because we want you to be the subject and not 1/y, you reciprocate both sides.

  • @dtorres333
    @dtorres333 8 лет назад

    for a question on my homework it asks on which interval is the solution defined. My professor said it is the largest interval that contains the initial value on which the solution is continuous. ANd the he showed me an example that didn't make sense: 1/(x-3)^2, y(0)=5 is (-infty, 3), but 1/(x-3)^2, y(4)=2 is (3,infty). I don't understand. Can you show me how to find the interval on the example of this video? Or the example my professor gave me. Please help I'm screwed otherwise.

      It's a balance between size of font and amount of text on the screen. If the font is too small then it's impossible to read on mobile devices.
