The forum discussion centers on identifying an error in the mark scheme (ms) related to the trigonometric problem of finding ##\tan \theta## in the form of ##a+b\sqrt{2}##. Participants confirm the existence of a mistake and suggest that showing intermediate steps, particularly in grouping radicals and simplifying the denominator, can clarify the issue. The context involves an international curriculum paper, indicating the importance of accuracy in educational materials.
PREREQUISITESStudents preparing for international mathematics assessments, educators reviewing mark schemes, and anyone interested in enhancing their problem-solving skills in trigonometry.
Yes. There is an error.chwala said:
I saw the mistake ... just wanted to counter-check myself... Cheers man!scottdave said:
