The second degree Taylor polynomial for a function $\displaystyle \begin{align*} f(x) \end{align*}$ centred at the point is $\displaystyle \begin{align*} (h, k) \end{align*}$ is $\displaystyle \begin{align*} f(x) = f(h) + f'(h) \, \left( x - h \right) + \frac{f''(h)}{2} \, \left( x - h \right) ^2 \end{align*}$.

Can you evaluate $\displaystyle \begin{align*} f(1), f'(1), f''(1) \end{align*}$?
 

FAQ: Taylor Series: Find 2nd Degree Series for x^2+y^2=4 at [1, -\sqrt[]{3}]

What is a Taylor Series?

A Taylor Series is a mathematical concept used to approximate a function using a polynomial. It is a way to represent a function as an infinite sum of terms, where each term is a derivative of the function evaluated at a specific point.

How is a Taylor Series useful?

Taylor Series are useful for approximating functions that are difficult to evaluate directly. They are also used in a variety of applications, such as in physics and engineering, to model and analyze real-world problems.

What is a second degree series?

A second degree series, also known as a quadratic series, is a Taylor Series that includes terms up to the second derivative of the function. It is a polynomial of degree 2 and is used to approximate functions with more accuracy than a first degree series.

How do you find a second degree series for a given function?

To find a second degree series for a given function, you need to first calculate the first and second derivatives of the function at a specific point. Then, you can use the formula for a Taylor Series to write out the series, including the derivatives and the corresponding coefficients. Finally, you can evaluate the series at the given point to get the second degree series.

How do you find the second degree series for the equation x^2+y^2=4 at [1, -\sqrt[]{3}]?

To find the second degree series for this equation at the given point, you need to first calculate the first and second derivatives of the function (x^2+y^2-4) at the point (1, -\sqrt[]{3}). Then, you can use the formula for a Taylor Series to write out the series, which will include the derivatives and the corresponding coefficients. Finally, you can evaluate the series at the given point (1, -\sqrt[]{3}) to get the second degree series.
