    How to know it needs to subs y=y1+1/z?

      Thank you
      Here I considered that y1 is as a first point on the curve and y2 is the second.

    Thank you sir! May I just clarify something, in the particular solution part, can I also use the bernoulli one to solve the problem?

      Yes, you can follow thru with the normal bernoulli sub, and since Ricatti has the y^2 term, this will always be be z^(1-2), or z^-1, which is 1/z. This is the reason why it is 1/z or z depending on the path you wish to take.
      When you solve for the linear portion of the bernoulli, you plug back in to find that 1/z = [whatever your result was]. In this case, you have 1/z = -2+ce^-x. So in the end, you are still doing the reciprocal.
      It’s the same, but I prefer doing the reciprocal at the end with Bernoulli instead of writing the fractions out when plugging in the y1(x) + 1/z into the starting equation.
      I’m just doing some differential equations for the hell of it, so this may have not reached you in time if you wanted to know this for a course you are taking 😅

    where did the Z^2 go? how does 3Z^2 on the left cancel out the 2Z^2 + 2Z^2 on the right?

    What if y1 is not given? How can we solve that?

    • @SkanCityAcademy_SirJohn
      @SkanCityAcademy_SirJohn  ปีที่แล้ว +2

      If y1(x) is not given, you need to find that by inspection and that is sometimes difficult to find, but usually it will be given.

    • @SkanCityAcademy_SirJohn
      @SkanCityAcademy_SirJohn  ปีที่แล้ว +1

      Yes you can, but it's easier reducing to linear.

      I think I explained that in the introduction, so after watching that on Bernoulli, you should know how to continue 🙏

    Please I have an article addressed ( Fast way to solve Ricatti equation) so
    y'_2y^2+3y=1 or
    y'=2y^2_3y+1 then A=2 , B=_3 and C=1
    dy/dx+(2Ay1+B)y=_A (Alsultani DE 2)
    dy/dx+[(2*1*1+(_3)]y=_2
    dy/dx_y=_2
    I.F=e^int (_dx)=e^_x
    ye^_x=_2int e^_xdx+c=2e^_x+c
    y=2+ce^x , 1/y=1/(2+ce^x)
    y2=y1+1/y=1+1/(2 +ce^x) answer
    Short time and simple way .

      Thank you very much
      I have 4 articles about the first order differential equations:
      1- New method to solve the differential equations of the first order which consist of three terms .
      2- Fast way to solve Ricatti equation.
      3- New methods to solve some types of the first order differential equations.
      4- Alsultani rules to find the particular solution of Ricatti's equation.
      These articles I published theme to help the students , mathematicians and the searchers.
      Note : I found that Bernoullies equation
      dy/dx+p(x)y=q(x)y^n is wrong so I put my differential equation
      dy/dx+P(x)y/n=Q(x)y^k , where k =1_n (Alsultani DE) instead of Bernoullies differential equation.
