frogger Posted May 7, 2012 Report Share Posted May 7, 2012 Hey, does anyone know what the red questions are in our maths books? Are these the 'extension' questions (as in, not on the syllabus)? Or did they just decide to go a little crazy and spice up the colouring? The ones that I'm talking about specifically are those in Chapter 21: Differential Calculus (they're spread throughout the chapter). Thanks for any help!
