One idea, seen from several sides.
Start with the drawing. Follow the steps. Try another possibility.
Expressions, equations and systems
Why can we remove the same number from both sides?
See step by step →Motion in a plane and projectile motion
Why does the projectile keep moving at the highest point?
See step by step →Derivatives and rates of change
What slope appears as the second point approaches the first?
See step by step →Labs to go further.
Connect lesson concepts to simulations with parameters and graphs.
