[tex]f(x)=x^4-2x^2+1\implies f(2)=9[/tex]
[tex]f'(x)=4x^3-4x\implies f'(2)=24[/tex]
[tex]f''(x)=12x^2-4\implies f''(2)=44[/tex]
[tex]f'''(x)=24x\implies f'''(2)=48[/tex]
[tex]f^{(4)}(x)=24\implies f^{(4)}(2)=24[/tex]
[tex]f^{(n)}(x)=0\text{ for }n\ge5\implies f^{(n)}(2)=0[/tex]
The Taylor expansion around [tex]x=2[/tex] is then
[tex]T(x)=\dfrac{f(0)(x-2)^0}{0!}+\dfrac{f'(0)(x-2)^1}{1!}+\dfrac{f''(0)(x-2)^2}{2!}+\dfrac{f'''(0)(x-2)^3}{3!}+\dfrac{f^{(4)}(0)(x-2)^4}{4!}[/tex]
[tex]T(x)=9+24(x-2)+22(x-2)^2+8(x-2)^3+(x-2)^4[/tex]
Taylor's series expansion of f(x) about x=2 was written using the expansion formula.
[tex]f(x)=x^4-2x^{2} +1[/tex]
[tex]f(2)=9[/tex]
[tex]f'(x)=4x^3-4x[/tex]
[tex]f'(2)=24[/tex]
[tex]f''(x)=12x^{2} -4[/tex]
[tex]f''(2)=44[/tex]
[tex]f'''(x)=24x[/tex]
[tex]f'''(2)=48[/tex]
What is Taylor's series expansion of f(x) about x=c?
Taylor's series expansion of f(x) about x=c is given by:
[tex]f(x)=f(c)+f'(c)(x-c)+\frac{f''(c)}{2!} (x-c)^2+\frac{f'''(c)}{3!} (x-c)^3+....[/tex]
So, Taylor's series expansion about x=2 will be given by
[tex]f(x)=f(2)+f'(2)(x-2)+\frac{f''(2)}{2!} (x-2)^2+\frac{f'''(2)}{3!} (x-2)^3+....[/tex]
[tex]f(x)=9+24(x-2)+21(x-2)^2+8(x-2)^3+....[/tex]
Hence, Taylor's series expansion of f(x) about x=2 was written using the expansion formula.
