Part 3/5:
The process of visualizing these multi-variable functions has been simplified remarkably. Simply typing a function such as "cos(x) + cos(y)" into Google search presents an interactive graph.
Interactive Features: Users can zoom in and out using the scroll wheel on their mouse, allowing for precise viewing of the function’s characteristics. Notably, this feature includes an animation option that helps visualize how the graph changes dynamically.
Customize Axes: Google’s graphing tool allows modifications to the axes. By clicking on the axis settings, one can adjust the range for a better view of specific trends or values within the function.
