sketch the graph of the function: f(x,y)= 1+2x^2+2y^2
The usage of polar coordinates must be useful: [rho,theta]=meshgrid(0:0.1:2,0:pi/60:2*pi); x=rho.*cos(theta); y=rho.*sin(thet...

how can I use partfrac command?
I suggest the following code: syms s; laplace(ilaplace((8*s^2+37*s+32)/((s+1)*(s+2)*(s+4))))
