1) f(x)=x^7-3x^5+5x^4+3; f'''(x); x=1:5
2) g(x)=e^(xsinx)+2ln(x^2+1); g''(x); x=-pi:pi/4:pi
3) h(x,y)=(x^2+y^2)/((x+y)^2); h(xy)(x,y);e valuate at all pairs(1,1),(2,2),(3,3),(4,4),(5,5)
4) t(x,y,z)=(x^3)(y^2)(z)+((x^2)+(y^2)+(z^2))^(1/2); t(xyz)(x,y,z); evaluate at the eight vertices of the cube with coordinates atx=+-1, y=+-1, z=+-1
