To solve this, students needed to work backwards:
They forgot that in similar triangles, sides are proportional, not the angles’ trig values. 2013 o level emath paper 1 answers
For example, a typical problem structure involved: To solve this, students needed to work backwards:
This question was a classic "process" question where the relied heavily on showing clear algebraic steps. Keep values to at least 4 significant figures
Do not round off intermediate steps. Keep values to at least 4 significant figures until the final answer (usually 3 s.f.). Units: Always check if the question asks for the answer in . 2013 had several "trap" unit conversions.
