9/09/2010 · Question 1 Consider a power series of the form ∞ y=∑ a_j x^j j=0 Solve the DE dy/dx – y = 0, IC: y(0) = 2 By taking only the first three nonzero terms, compute y(x) for a given value of x.... This series shows how to solve several types of Calculus limit problems. Special cases of limits are solved and the related graphs are described. Solving Calculus limit and derivative problems are made understandable in this guide. See examples of how to find the derivative using derivative rules.

**Use Power Series method to solve y'' 2xy' + y = 0**

I've only seen the power series method applied to initial value problems, never to boundary value problems. If you can tell me how to do it mathematically, I can probably help you write the code. But I doubt it can be done mathematically. unwanted ads for sex in inbox how to stop +1 This is a good start. Power series solutions, though, are frequently used to obtain recursion equations for the coefficients (of any solution that might be analytic within a neighborhood of the point of expansion).

## How To Solve Power Series Problems

Since the method for finding a solution that is a power series in x 0 is considerably more complicated if x 0 is a singular point, attention here will be restricted to power series solutions at ordinary points.

- The series solutions method is mainly used to find power series solutions of differential equations whose solutions can not be written in terms of familiar functions such as polynomials, exponential or trigonometric functions.
- 9/09/2010 · Question 1 Consider a power series of the form ∞ y=∑ a_j x^j j=0 Solve the DE dy/dx – y = 0, IC: y(0) = 2 By taking only the first three nonzero terms, compute y(x) for a given value of x.
