derivative: The instantaneous rate of change, also the gradient of a tangent.
iteration: A repeated update in which each new approximation is calculated from the previous one.

IA · School-supervised mathematical exploration

Planning a mathematical exploration: A condition adopted to make a mathematical model possible and whose effect should be evaluated.

assumption: A condition adopted to make a mathematical model possible and whose effect should be evaluated.

Current first-assessment-2021 course: AI permits technology on both papers.
External examination contributes 80%; the school-supervised mathematical exploration contributes 20%. SL papers are 40% each; HL Papers 1/2 are 30% each and Paper 3 is 20%.
Public briefs establish structure, not full official learning objectives. School access to the current full guide, formula booklet and calculator policy is required to certify complete parity.
Do not apply the revised 2029 marks, paper timing or exploration criteria to current cohorts.

Official question-bank boundaries, scheme alignment and all objective-level teaching coverage require the recorded review; no practice registry promotion.
The authored diagnostic assessments are not full-length qualification mocks.
The complete current IB guide, formula booklet, authenticated exploration criteria and full SL/HL objective codes are unavailable in the public archive.
