Solving Initial Differential Question: Finding General Solution for y

AI Thread Summary
The discussion focuses on solving the initial differential equation y' = ty(4-y)/(1+t). The user has isolated variables and integrated, resulting in a logarithmic expression. To express the general solution explicitly for y, it is suggested to combine logarithmic terms using properties of logarithms, specifically the quotient rule. The manipulation leads to the equation ln(4y/(4-y)) = 4t - 4ln(t+1) + C. The discussion emphasizes the importance of algebraic manipulation and logarithmic properties to isolate y effectively.

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
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
