Where marks go in AA SL Unit 3

From the IB subject reports we summarise on AA SL Examiner Insights, in our own words:

• Trigonometric equations: one solution only, and exact values not known. Sketch the graph over the given interval and count the solutions before you start. Learn the exact values for 0, π/6, π/4, π/3, π/2 and their related angles.
• GDC in the wrong angle mode, and degrees in radian formulas. Check the mode at the start of every question: radians for calculus, trigonometric models and the arc and sector formulas; degrees for bearings and triangle problems given in degrees.
• Modelling in context: not setting up the expression, and answers that ignore the context. Translate the words first: fastest rate means maximise the derivative; closest means minimise a distance. End with a sentence in the units and form the context needs (a year, a whole number, one value).

The questions here are original, written in the style of IB papers with IB-style mark schemes; for real papers see the IB Maths AA SL past papers page.
