The governing equation: ∂Ω/∂t = (∂2Ω/∂x2)-DH(∂Ω/∂x) Find the steady-state solution Ω(x) from the boundary conditions: Ω(0) =1,Ω(1)=0
(*The dot next to the N means N prime) A lake is stocked with an initial population of fish N0 (at t = 0). Over time the fish population N(t) grows according to the differential...
given in series circuit L=1H, R=110ohm, C=0.001F, v=90V. Find the resultant current when the switch is originally open and it is closed for 1s. then it is open again when t=1. use laplace transform...
How do I solve the differential equation y'(x)+2y(x)/x=6, when y(x0)=y0; x0=-2 and y0=-4.
Consider the initial value problem: y'+(2/3)y=1-(1/2)t, y(0)=yο. Find the value of yο for which the solution touches, but does not cross, the t-axis.

Solve the differential equation e^x dx+(e^x cot(y)+2y csc(y))dy=0. M=e^x N=e^x cot(y)+2y csc(y) My=0 Nx=e^x cot(y) Obviously isn't exact. What to do next?
Solve the differential equation dx+(x/y-sin(y))dy=0. I know that the integrating factor is y. y dx+x dy-ysin(y) dy=0 d(xy)-ysin(y) dy=0 How do I integrate this?
Differentiation. i need help with this problem.
I'm having trouble doing a linear laplace transform. The question is solve for ivp y'' -2y' +2y = cos t y(0) = 1, y'(0) = 0
For the differential equation: 2(1-x)y''-3y'+(y/x)=0 What are the singular points and determine whether they are regular or irregular? Then find the roots of the indicial equation Thank...
By using the Green's function, solve: y''-αy =e^(-αx) with initial conditions y(0)=y'(0) = 0 thank you to whoever can do this in detail for me :)
i dont know how to deal with e and sine in the same equation.
Please could someone show me a step by step method that works for all these kind of problems.
