Inviscid means flow of a fluid that is assumed to have no viscosity (i.e no firction forces).

If we assume drag is skin-fiction drag then the effects of a real fluid flow are the result...
Select the correct solution for dy/dx = 1/[(4y)*(x^3)]
a) x^4
b) x^(-1/4)
c) 1/(x^4)
d) x root 4
Choice D means instead of cubic root, to the power 4 root
Plz explain how to do this. I tried separating variables and integrating the choices but it didn't work. Mayb I should...
Suppose rabbit populations grow exponentially with a growth rate of 20% per year. If P(t) is the population at any time t and 1000 is the initial (t=0) population of rabbits, what is the population of rabbits in 10 years?
Use the DE model: P ' = kP with k = .1 and P(0) = 1000.
Plz help me
Find values of the constants a and k so that y(x) = ax^k solves the differential equation;
(dy/dx)^2 + [(3y^2)/(x^2)] + [(2y)/(x^4)]
I tried substituiting ax^k into the DE but it did not work. I need to separate x and y but I cannot do it then I need to integrate it I think. I just...
