a) On January 1 2000, the park estimated that they had 500 deer on their land. Two years later, they estimated that there were 550 deer on the land. Assume that the number of deer was changing exponentially,...

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...
Solve by series of expansion: Put in closed form: 2xy'' + (1-2x^2)y' - 4xy = 0
xy + y' = 160x
Learning about homogeneous functions and this was the example given to practice this topic.
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
A toilet cistern was emptied and refilled and the following data obtained: t = [ 0 2 3 4 5 8 14 23 28 34 41 53 74] time in seconds h = [17.5 11 7 4 2 0.5 5 10 12 15 16 17 17.5]; height...
Please could someone show me a step by step method that works for all these kind of problems.
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.
i dont understand this at all!! help me with this asap!!
csc = cosecant confusing!!
the might be the most confusing question for me, in my opinion.
before using differentiation, do I have to FOIL the problem first? i need help.
log_5 means that the base is 5. ((3x^2) - 4x) is counted as the exponent for e. * means multiply
Differentiation. i need help with this problem.
(*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...
