WebJan 2, 2024 · The following example can be used for solving a set of two differential equations using lsode. The function is defined by: function x_dot = f (x, t) r = 0.15; k = 1.6; a = 1.25; b = 0.12; c = 0.89; d = 0.58; x_dot (1) = r*x (1)* (1 - x (1)/k) - a*x (1)*x (2)/ (1 + b*x (1)); x_dot (2) = c*a*x (1)*x (2)/ (1 + b*x (1)) - d*x (2); endfunction WebJan 7, 2015 · Firstly, your equation is apparently (3x-1)y''- (3x+2)y'- (6x-8)y=0; y (0)=2, y' (0)=3 (note the sign of the term in y). For this equation, your analytical solution and definition of y2 are correct. Secondly, as the @Warren Weckesser says, you must pass 2 parameters as y to g: y [0] (y), y [1] (y') and return their derivatives, y' and y''. songs about thanking your parents

WebBut note that in the second, we have Nc * (K-N), while in the first we have Nr * (1 - N/K). c is NOT equal to r. In fact, c = r/K. Sal Khan used dP/dt = kP (a - P) which is the same as the second form, dN/dt = Nc * (K-N). Here, P is N, a is uppercase K, and lowercase k is c. Ask if you have questions! And let me know if I made any errors. Thanks! WebApr 10, 2024 · 1. Solve the logistic equation dtdN=aN−bN2,N (0)=N0. Then find the value of Nmax. Question: 1. Solve the logistic equation dtdN=aN−bN2,N (0)=N0. Then find the value of Nmax. Show transcribed image text Expert Answer 1st step All steps Final answer Step 1/3 To find Nmax, we need to first find the equilibrium solutions for the differential … Webthe logistic model. The logistic model is given by the formula P(t) = K 1+Ae−kt, where A = (K −P0)/P0. The given data tell us that P(50) = K 1+(K −5.3)e−50k/5.3 = 23.1, P(100) = K 1+(K … small farm technology
