If the calculator runs into an error during computation, an error message will be displayed instead of the answer and steps.The Vanderbeekers to the Rescue - Old Colony Library Network. The solution steps are printed below the answer when a user with access is logged in. Once a final answer is calculated, it is printed in the solution box. These "states" are used to build the solution steps which mirror that of a ratio test. The routine also saves the state of the limit/expression throughout the process. These operations mirror the ratio test's steps. When you click the "calculate" button, the solving routine is called and progresses through several symbolic operations. Because the calculator is powered by JS code, it runs entirely inside your browser's built-in JS engine and provides instant solutions and steps (no page reload needed). It also utilizes a JS-native computer algebra system (CAS) which performs some algebraic steps during the computation process. The calculator on this page is written in three common web frontend languages: HTML, CSS, and JavaScript (JS). The ratio test uses a ratio of the power series and a modified n + 1 version of itself to solve for a radius of x which satisfies the convergence criteria. The ratio test is simple, works often, and is used by the calculator on this page so that is what we will learn about here. There are several tests we may use to solve for radius of convergence, including the ratio test and the root test. This is just one example of a use for the radius of convergence, and there are many more applications that work behind the scenes inside computer software to help us every day!Ĭalculating the Radius of Convergence of a Power Series This is great news because it means the power series will converge everywhere and can be used for e x with all possible input x values.īy programming this routine into a computer, we enable it to quickly and accurately solve for the value of e x with any value of x. If we check the radius of convergence for this power series, we find that it is r = ∞ and that the interval of convergence is ∞ < x < ∞. Luckily, the power series f(x) = x n⁄ n! represents the expression e x when carried out to many terms. Because of how computers store floating-point numbers and create round-off error, this process can take the computer very long and can give an inaccurate answer. If we are evaluating e x with a large exponent, a calculator's computer has to multiply large, messy numbers by large, messy numbers many times over. For example, the seemingly simple e x button commonly found on hand calculators is one that the calculator's computer cannot easily and accurately solve directly.īy learning how to find the radius of convergence, we can program an otherwise incapable computer to indirectly find the value of e x via use of a power series. Compared to humans, computers are really good at certain types of calculations but have difficulties performing other types of calculations.
