These are the important concepts of calculus and the “knowledge” chunks where they appear in. Each chunk of knowledge is also part of a lesson so we show that relationship explicitly.

}

derivative → derivatives; number → functions; function → functions; function → derivatives;

derivatives → optimization; functions → solving_equations;

functions_and_inverses → solving_equations;
