[AAHL][AASL][AIHL] Trigonometric functions - Part 5

-

First post in 2022!

Hey there. If you're looking for more trig functions torture fun, hang on tight. Today we'll put the properties of trig functions into solving more realistic problems.

Surprisingly these questions are generally very poorly done, simply because

  • Kids cannot map the relative height on the wheel with the height of the trig functions
  • Kids cannot interpret the properties of trig functions properly because the wordings are bad
  • Kids' understanding of functions is weak, leading to their inability to recognise what to do and what to substitute where
  • and 7749 other reasons.

Here's my two cents that might help y'all to avoid the common misconceptions, especially the second bullet point. You should be very solid at properties of trig functions before reading on.

[Survival Guide] AASL Version

-
Hello hello hello! I am now back with a fancy project - the ultimate Survival Guide for AASL. If you're struggling and you want an all-in-one Survival Guide, this  is it! What's in the Revision Guide? Packed inside this booklet are a series of statements for you to check if you're prepared to get a solid 4 (or even a 5!) on the official exams. You'll also have questions on the right column to check if you know what you're doing. Answers not included. I know y'all don't have time to do all the stuff in hundreds of pages of the RG, and it's hard to find a revision checklist like this online, so I might as well make it available for everyone interested. c; Disclaimer I've tried my best to only include topics that usually pop up quite early on the exams, but do not sue me if the questions on the exam do not exactly match with my preds.  Compacting two years of content in a 15-page document means some content will be left out deliberately  (you don't

A collection of topic tests that I've ever written on the website. Unit Tests Occasionally featuring questions from endless inspirational sources. Answers included. Nombre complexes (AAHL seulement)  Complex number. The test is in English, don't worry. Contains some wonderful questions that might require the use of integration. Logarithms (AASL/AAHL)  Logarithmic, exponential and rational functions. Further transformations for AAHL students. Proofs, binomial and more (AASL/AAHL)  A list of miscellaneous topics that don't fit anywhere. Quadratics (AASL/AAHL)  Combined algebra and quadratics - an updated version will arrive soon. Quadratics (AISL/AIHL)  Slightly different from the former because of the emphasis of the courses. Sequences and series (all four courses)  Covering two types of series studied in depth in IB: arithmetic and geometric. Knowledge of logarithms was required if memory serves me. Version 2 Sequences and series (AASL/AAHL)  A more general approach to sequ
