1) Find the general solution of di = Ay where Then sketch the phase portrait in the x-y plane, where Finally, classify the equilibrium solution at the origin as a source, spiral sink, etc. 2) Repeat for the matrix | 3 -31 -2 -2] 3) Repeat for the matrix 4 — 4) Repeat for the matrix [95 -9 15 but you don't need to sketch the phase portrait.
Consider the system x'=xy+y2 and y'=x2 -3y-4. Find all four equilibrium points and linearize the system around each equilibrium point identifying it as a source, sink, saddle, spiral source or sink, center, or other. Find and sketch all nullclines and sketch the phase portrait. Show that the solution (x(t),y(t)) with initial conditions (x(0),y(0))=(-2.1,0) converges to an equilibrium point below the x axis and sketch the graphs of x(t) and y(t) on separate axes. Please write the answer on white paper...
1. Draw the orbit analysis or phase portrait of f(x) = x3 - X. 2. Find the neutral fixed point of g(x) = x - *3. Use graphical analysis to determine if the fixed point is weakly attracting, weakly repelling, or neither.
VBA The projectile motion equations are,x=x0+v0*cos(θ)*t, y=y0+v0*sin(θ)*t+0.5*g*t^2 where x and y are the current position at time t, x0 and y0 are the projectile’s initial position, v0 is the projectile’s initial speed, θ is the initial firing angle of the projectile, and g is the gravitational acceleration which is -9.81 m/s2 near Earth’s surface. The user (me) will input the initial x-position (m), y-position (m), speed (m/s), the firing angle (in degrees) in cells F2-F5 on Sheet2. Create a run...
