Power Series Power series are one of the most useful type of series in analysis. For example, we can use them to define transcendental functions such as the exponential and trigonometric functions (and many other less familiar functions). 6.1.

Frequently Asked Questions

How to find the power series expansion of sin x?

In order to use Taylor’s formula to find the power series expansion of sin x we have to compute the derivatives of sin(x): sin�(x) = cos(x) sin��(x) = − sin(x) sin���(x) = − cos(x) sin(4)(x) = sin(x). Since sin(4)(x) = sin(x), this pattern will repeat.

How to calculate Taylor's series of sin x?

Taylor’s Series of sin x In order to use Taylor’s formula to find the power series expansion of sin x we have to compute the derivatives of sin(x): sin (x) = cos(x) sin (x) = − sin(x) sin (x) = − cos(x) sin(4)(x) = sin(x). Since sin(4)(x) = sin(x), this pattern will repeat.

When does the power series converge for every x x?

In this example the root test seems more appropriate. So, So, since L = 0 < 1 L = 0 < 1 regardless of the value of x x this power series will converge for every x x. In these cases, we say that the radius of convergence is R = ∞ R = ∞ and interval of convergence is − ∞ < x < ∞ − ∞ < x < ∞ .

Why are power series useful in function analysis?

Power series. Power series are useful in analysis since they arise as Taylor series of infinitely differentiable functions. In fact, Borel's theorem implies that every power series is the Taylor series of some smooth function.
