This Newton's Method interactive also includes:
- Newton's Method
- Student Reference
- Join to access all included materials
Use an iterative process to find an approximation of a square root. Pupils use the interactive to find an approximation to find the positive root of a quadratic function with Newton's method. With the graphs, learners position the tangent line to get better approximations of the roots of the function.
