    HL Core Syllabus Content
    Thank you for your last suggestion! HL Trig syllabus doesn't have "general solution" concept. To what extent we need to complete reciprocal trig functions? for example, basic reciprocal graphs, transformations etc.

    Jacqueline, Thank you for your question. I just took a look at the worksheet - and answers are given for 6c and 6d. Is there something missing? or something incorrect? I'm sorry - but I could not see anything missing. Let me know if I missed...

    Raj, I have not yet put any formal advice yet on my site with regard to IB unit planners. I hope to in the near future. It's important to point out that (at least now) the IB does not require explicit unit planning but does strongly recommend...
  • Raj, Good question. Although it's a good thing to know, students are not required to find a general solution to a trig equation. This is not in the current syllabus, and to the best of my knowledge it will not be in any of the new courses...
