Question

(USING MATLAB)

Given two differential equations X= sin(t)(exp(cos(t))-2cos(4t)+sin(t/12)^5)

And Y = cos(t)(exp(cos(t))-2cos(4t)+sin(t/12)^5) where 0<t<20pi is a vector of 5000 points created by using (linspace) command :

Write script to plot X and Y with red color ?

Answer 1

code:

t=linspace(0,20*pi,5000);
x=sin(t).*(exp(cos(t))-2*cos(4*t)+sin(t/12).^5)
y=cos(t).*(exp(cos(t))-2*cos(4*t)+sin(t/12).^5)
subplot(1,2,1)
plot(t,x,'r')
subplot(1,2,2)
plot(t,y,'r')

figure:
