What is Heun's Method?
Heun’s Method is a numerical analysis method in which the iterative procedure is used to solve ordinary differential equations (ODE).
Heun’s method is also called the modified or improved Euler’s method which gives the most stable or precise solution. This method is an improved version of simple Euler’s method which is why it gives an accurate solution.
Further, for yours needing assistance with differentiating composite functions, our chain rule solver provides a convenient tool for computing derivatives using the chain rule. Whether you're a student learning calculus or a professional needing to differentiate functions quickly, this calculator offers an efficient solution.
Formula Used by Improved Euler’s Method Calculator
Heun’s method formula is derived from Euler’s method to enhance its accuracy rate of the estimated value of y. The improved Euler method calculator uses the following formula for numerical analysis:
$$ y_{n+1} \;=\; y_n + \frac{h}{2} \biggr[ f(x_n , y_n) + f \biggr(x_{n+1},y_n + h\; f(x_n, y_n) \biggr) \biggr], \; \; \; n \;=\; 0,1,2,..... $$
$$ p_{n+1} \;=\; y_n + h\; f(x_n , y_n), $$
$$ y_{n+1} \;=\; y_n + \frac{h}{2} \biggr[f(x_n, y_n) + f(x_{n+1}, p_{n+1}) \biggr], \; \; \; n \;=\; 0,1,2,.... $$
Whereas,
- yn+1: new approximate value of y
- yn: current approximate value of y0
- xn: average slope at the x-axis
- pn+1: an immediate prediction value
- h: step size or number of steps n
The formula incorporates a two-step process for each iteration, allowing for a more accurate estimation of y compared to the basic Euler method. By considering the slope at both the current point and a predicted point ahead, the Improved Euler's Method effectively reduces errors and improves the precision of the numerical approximation.
Moreover, By understanding the formula utilized by the Improved Euler's Method Calculator and exploring related tools such as the derivative calculator product rule, you can enhance their problem-solving capabilities in numerical analysis and calculus.
Understanding the Working of Heun's Method Calculator
The Improved Euler calculator uses the simplest and easiest method to solve the ordinary differential equation using an improved Euler’s method. This is because our tool has advanced features in its software that allow you to solve various types of numerical values instantly.
When you give the input value for getting the solution of an ordinary differential equation in the heun method calculator, it will identify the given data first. After identification, it adds all the values in Heun’s method formula or Euler’s modified method.
After calculation, it gives the first value of y1 after putting 1st iteration, then it again finds the value of pn+1 value and again adds iteration to the formula to get the solution of y2 value. In this way, this cycle is going on till the required y value is not achieved.
You can check out the given example to visualize the concept of Heun’s method practically so that you can easily grasp it for better understanding. Remember your question solution depends on the n number of y values that are given in Heun's method question.
Additionally, if you are in need of assistance with differentiating quotient functions, ourderivative calculator using quotient rule provides a convenient tool for accurately computing derivatives using the quotient rule.

$$ k_{22} \;=\; f(x_3, y_2 + h\;k_{12}) \;=\; f \biggr(.3, .672734445 + .1(-1.340106330) \biggr) $$
$$ f(.3, .538723812) \;=\; -2(.538723812) + (.3)^3 e^{-.6} \;=\; -1.062629710 $$
$$ y_3 \;=\; y_2 + \frac{h}{2} \biggr( k_{12} + k_{22} \biggr) $$
