Differential equations question
Differential equations question
I have been asked to prove the below function satisfies heat equation. u(r,t)=2Uπ∑n=1∞ {(−1)^n+1}(1/r)sin(nπr)e^−n^2π^2t I have tried to equate ∂u/∂t = ∂^2u/∂x^2 however both...
m.(d2x/dt2) + R(dx/dt) -kx=0 when m= x2 , R= x-x2 , k=1 I have no idea of what method to use to get the solution.
Supposed to find using inspection method
V=10*t-(t2)/20 a) State the logical domain of the function, i.e. the values of t during which soil is being removed. b) At what rate is the soil is being removed at the end of...
Please could someone show me a step by step method that works for all these kind of problems.
I'm confused on this topic in my Diff Eq class.
How do you solve this differential equation, (x-y2 )dx + 2xy dy =0
Suppose that 120 deer are placed in a protected region. If the region can support a maximum deer population of 500, then the bounded growth model for the deer population gives us which differential...
Supply voltage of a DC motor is given by: V(t)=Ri(t)+L (d i(t))/dt+kω(t) Here i(t) is the current through the coil, R is the resistance, L is the inductance of coils, ω(t) is the angular...

How can i get this?
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...
Can u help me solve this problem: (cos y) dy/dx - sin(y) = x, where y(0)=0
Name the title of the book, author, edition, ISBN number. Also, what bookstore sells used college textbooks for this? And what math should I take after Differential Equations for physics and engineering...
