SUMMARY

The discussion focuses on solving the initial differential equation y' = ty(4-y)/(1+t). The user successfully isolated the variables and integrated, resulting in the equation (1/4)ln(4y) - (1/4)ln(4-y) = t - ln(t+1) + C. To express the general solution explicitly for y, participants suggest using algebraic manipulation and properties of logarithms, specifically combining logarithmic terms to derive ln(4y/(4-y)) = 4t - 4ln(t+1) + C.

the initial diffferential question is
y' = ty(4-y)/(1+t)

i isolated the variables and integrated

what i have is
(1/4)ln4y - (1/4)ln(4-y) = t - ln(t+1) + c

now i am supposed to express the general solution explicitly but i am don't know how to solve for y. any sort of suggestion would be greatly appreciated. thanks.

Combine the logs on each side noting ln a - ln b = ln (a/b) and proceed from there! :-)
 


To solve for y, you will need to use algebraic manipulation and properties of logarithms. First, you can combine the two logarithmic terms using the properties of logarithms, specifically the quotient rule. This will give you:

ln(4y/(4-y)) = 4t - 4ln(t+1) + C

Next, you can use the property of logarithms that states ln(a/b) = ln(a) - ln(b). This will give you:

ln(4y) - ln(4-y) = 4t - 4ln(t+1) + C

Now, you can use the property of logarithms that states ln(a) - ln(b) = ln(a/b). This will give you:

ln(4y/(4-y)) = 4t - 4ln(t+1) + C

Next, you can use the property of logarithms that states ln(a/b) = ln(a) - ln(b). This will give you:

ln(4y) - ln(4-y) = 4t - 4ln(t+1) + C

Now, you can use the property of logarithms that states ln(a) - ln(b) = ln(a/b). This will give you:

ln(4y/(4-y)) = 4t - 4ln(t+1) + C

Next, you can use the property of logarithms that states ln(a/b) = ln(a) - ln(b). This will give you:

ln(4y) - ln(4-y) = 4t - 4ln(t+1) + C

Now, you can use the property of logarithms that states ln(a/b) = ln(a) - ln(b). This will give you:

ln(4y) - ln(4-y) = 4t - 4ln(t+1) + C

Now, you can use the property of logarithms that states ln(a/b) = ln(a) - ln(b). This will give you:

ln(4y) - ln(4-y) = 4t - 4ln(t+1) + C

Now, you can use the property of logarithms that states ln(a/b) = ln(a) - ln(b). This will give you:

ln(4y) - ln(4-y) = 4t - 4ln(t+1
