Complex and Parametric Motion Lesson Set

Use the complex-and-parametric topic page, the authored starter track, one parametric-motion checkpoint, and the vectors topic page so the plane-based math branch stays compact and teacher-usable.

About this guided path

Open the authored rationale, highlights, and educator framing only when you need more context than the next step.

The topic page frames the complex-plane and motion-from-equations branch first, the starter track preserves the authored order from complex numbers into unit-circle rotation, polar coordinates, trig identities, inverse-angle recovery, and parametric motion, the closing challenge forces one honest path-versus-traversal checkpoint, and the vectors topic page shows where the same plane habits can widen next.

Educator note

Best when learners should deepen the math slice beyond graph transformations without jumping straight into full mechanics.

Guided path

Follow the next steps in one authored order.

Each step still opens an existing topic page, concept bench, track, or challenge. This page only keeps the authored order legible.

4 steps across 9 concepts, with one clear first move.

Next stepTopic page

Open the complex-and-parametric topic page

Anchor the lesson in the canonical plane-based math branch before the deeper sequence starts.

  1. 1Topic pageNot startedNext step

    Open the complex-and-parametric topic page

    Use the topic page to frame complex-plane geometry, rotation, polar coordinates, and motion from equations before the collection narrows into the authored order.

    Open this topic page before the linked concepts start accumulating saved progress.

  2. 2Starter trackNot started

    Run the Complex and Parametric Motion starter track

    Keep complex numbers, unit-circle rotation, polar coordinates, and parametric motion in the authored order already shipped in the catalog.

    Complex Numbers on the Plane is the next best step inside Complex and Parametric Motion.

    Close with the parametric-motion checkpoint

    Finish on the existing challenge where a tall traced curve and a fast-moving point have to be read together instead of as the same idea.

    No saved challenge activity yet for this step.

    Open the vectors topic once the plane language feels stable

    Use the vectors topic page when the same coordinate habits should widen into addition, projection, and later mechanics.

Check your starting point

Open the diagnostic only when you need help deciding whether to continue, restart, or skip ahead inside this path.

Entry diagnostic

Decide where to enter this path without opening a second testing system.

Reuse the complex-plane quick test plus the unit-circle sign and polar x-y checkpoints to decide whether this lesson set should start at the topic page or jump straight to the parametric-motion capstone.

Check the plane-to-motion bridge before you replay the whole branch

Start from the opening step

No saved diagnostic checks are available yet, so the opening step is still the best entry into the collection.

Uses the same local-first concept, challenge, and track facts already saved in this browser.

  1. Quick testNot started5 questions

    Complex-plane quick test

    Check whether points, vectors, magnitude, and argument already read as one object on the same plane.

    No saved quick-test result yet.

    Complex numbers
  2. ChallengeNot started5 checks

    Catch the first sign flip

    Start from the axis-crossing view, then move just into Quadrant II so cosine is negative while sine is still clearly positive. Keep the guides and sign map on so you can see exactly why the signs differ.

    No saved checkpoint attempt yet.

    Unit circle rotation
  3. ChallengeNot started6 checks

    Quadrant II coordinate check

    Build a point in Quadrant II where the leftward x-projection has larger magnitude than the upward y-projection. Keep the coordinate guides on so r, θ, x, and y stay tied to the same point.

    No saved checkpoint attempt yet.

Path tools

Share or assign this path

Copy a stable collection link or save a compact bundle only when you need to relaunch or share the sequence elsewhere.

Share this collection

Copy a stable collection link. Links stay public and never include saved progress or private account state.

Shareable concept bundle

Package a compact launch path from this guided collection.

Keep the bundle lightweight: choose the collection entry points that matter, give the package a clear summary, and share one stable link back into the same topic, concept, track, and challenge surfaces that already exist.

Bundle progress below stays local-first and never rides along with the shared link.

Included entry points

Uncheck anything that should stay outside this shareable bundle.

Assignment mode

Save the current bundle selection as a stable assignment link.

This stays intentionally small. The assignment stores the selected guided-collection steps and an optional note, then learners reopen the same concept, track, topic, and challenge surfaces through one stable entry point.

Sign in to save a stable assignment link. Signed-out bundle sharing above still stays public.
