1 1 The ideal prediction line would hit the curve at its next predicted point. Example Problem. Articles that describe this calculator. One way is to use the slope at to calculate an initial estimate . by way of Heun's method, is to first calculate the intermediate value y ~ i + 1 {\displaystyle {\tilde {y}}_{i+1}} and then the final approximation y i + 1 {\displaystyle y_{i+1}} at the next integration. However, even when extremely small step sizes are used, over a large number of steps the error starts to accumulate and the estimate diverges from the actual functional value. No matter what question you have, our expert teachers will have an answer for you in no time. Using the principle that the slope of a line equates to the rise/run, the coordinates at the end of the interval can be found using the following formula: The accuracy of the Euler method improves only linearly with the step size is decreased, whereas the Heun Method improves accuracy quadratically Heun's method is an attempt to use information about the slope at both end points to find the average slope.
