Vector Addition Interactive Demo
Vector Addition Interactive Demo is a free, interactive learning demo from the Precalculus course on Lykke. It helps you build intuition for Vector components and magnitude, Scalar multiplication, Vector addition and subtraction, Rectangular and polar conversion. Play with it directly in your browser — it features 2 sliders, 1 toggle, direct drag interaction and a live visual canvas. This demo lives in the “Vectors” section of the course.

How to use this demo
- Drag the “Scale (k):”, “Snap to Grid” sliders to change the inputs and watch the result update live.
- Click and drag directly on the canvas to manipulate the scene.
- Toggle the checkboxes to show or hide layers and compare cases.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Vector components and magnitude
- Scalar multiplication
- Vector addition and subtraction
- Rectangular and polar conversion
Frequently asked questions
What does the Vector Addition Interactive Demo demo do?
Vector Addition Interactive Demo Vector u Scale (k): 1.0 Snap to Grid Drag the arrow heads to move vectors Drag vectors to explore addition. Vector Addition Interactive Demo lets you explore this hands-on instead of only reading about it.
What Precalculus concept does Vector Addition Interactive Demo teach?
Introduction to vector quantities, covering components, magnitude, and operations like addition and scalar multiplication. It focuses on Vector components and magnitude, Scalar multiplication, Vector addition and subtraction, Rectangular and polar conversion from the “Vectors” section.
What can I control in Vector Addition Interactive Demo?
The “Scale (k):”, “Snap to Grid” sliders change the key inputs; you can drag elements directly on the canvas; toggles show or hide layers so you can compare cases. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does Vector Addition Interactive Demo fit into the Precalculus course?
The Client Challenge Precalculus course is a comprehensive curriculum designed to bridge the gap between high school algebra and college-level calculus. It covers ten core units ranging from composite functions and trig… This demo is the interactive piece for the “Vectors” section.
