Find the Solution to dy/dx = 3y-3y2

Click For Summary
SUMMARY

The explicit solution to the differential equation dy/dx = 3y - 3y² is derived through separation of variables. The integration process involves the equation dy/(3y - 3y²) = dx, leading to (1/3)log(y) - (1/3)log(1-y) = x + c. The final step requires exponentiating both sides to isolate y. This method confirms the solution includes singular solutions as required.

Homework Statement



Find the explicit solution of dy/dx = 3y-3y2

Be sure to include any singular solutions in your answer

Homework Equations



Not sure...

The Attempt at a Solution



dy/dx = 3y-3y2
dy/(3y-3y2)=dx
∫(1/(3y-3y2))=(1/3)logy-(1/3)log(1-y)
∫(dx) = x + c

x+c = (1/3)logy-(1/3)log(1-y)

I'm really not even sure I'm on the right track here.

Appreciate the help.

Hi Phox! :wink:

Looks ok so far. :smile:

Now do e-to-the to both sides, and solve for y. :wink:
