Derivation of Unary Function and Taylor Expansion

函数求导

1 2	syms x diff(f(x), x)

1	diff(f(x), x, n)

1	ys = diff(y, t) / diff(x, t)

F(x, y) = 0

1	ys = - diff(F, x) / diff(F, y)

x在x0处的n阶泰勒展开式

1 2	syms x taylor(f(x), x, x0, 'Order', n+1)

默认为5阶

1 2	taylor(f) # 在x = 0处的5阶泰勒展开 taylor(f, x, a) # 在x = a处的5阶泰勒展开
