What Can Sage Do?• Graphs f1=-x+2
f2=1/x^2
f=piecewise([[(-1,1),f1],[(1,3),f2]])
f.plot()
• Calculate limits
limit((x^2-25)/(x-5),x=5)
derivativesf=sin(x^3)+x*cos(x)
diff(f,x) // or diff(f,x,n) to find the nth derivative
integralsintegral(3*x^2,x)
integral(x*sin(x^2),x,0,pi/2)
• SAGE can verify laws the product rule function('f, g‘)
diff(f(t)*g(t),t)
and the quotient rule diff(f(t)/g(t), t) AND MUCH MORE!!!
