Hello! I am trying to graph the following: 

dx/dt = -10*x + 10*y 
dy/dt = r*x - y - x*z 
dz/dt = -(8/3)*z + x*y 

where x, y, and z are all functions of time (t). Solve the equations subject to the constraint that r = 25 and the initial conditions that at t = 0, x = -1, y = -1, and z = 1. 

This is my code:
DE*plot3d({d*x(t)/dt = -10*x(t...
