taylor(function, x, x0, n)
calculates the n
-th Taylorpolynomial
in the symbolic variable x
at the point x0
.
>> syms x >> taylor(log(x),x,1,1) ans = x-1 >> rat( taylor(exp(x),x,0,6)) ans = 1/720*x^6+1/120*x^5+1/24*x^4+1/6*x^3+1/2*x^2+x+1 >> float( taylor(x^3*sin(2*x+pi/4),x,pi/8,2)) ans = 1.057*x^2-0.36751*x+4.1881E-2
