Write a C++ or a python code to solve the following initial value problem ordinary differential equation using Euler method over the interval [0 10) with 10time steps. Please make plots using excel or MATLAB for the output (y vs time) A) y'=-v-v? : y(0)=1 If that exact solution was y(t) = 1/(-1 + 2e"). What is the absolute error at y(10). (5 points) B) The following two equations represent the toggle switch genetic network. (5 points) du/dt = a1/(1+ v) - U dv/dt = 22/(1+uY) - v where; u(O) = 0; V(C) = 0;a1 = 2, a2 = 4, B = 2, Y = 2 x1=2, 2=4, B = 2, y = 2
