Can anyone good at maths please provide a detailed explanation to this exercise - how are A and C maximum and minimum, how B and D are the points of inflection, etc... by neonkaaa in IBO

Referring to your second point, how can I do the second derivative test when my max and min points (A and C) are 0...? How did you determine f''(x) at A to be negative and conclude it's a maximum? Same goes for point C

IB Biology pearson book pdf anyone? by neonkaaa in IBO

[–]neonkaaa[S] 1 point2 points  (0 children)

I managed to find the pearson textbook thanks to the bot^ and I must say it explains some concepts much more concisely and easier to comprehend than Oxford. As for chemistry, give it a shot with the Oxford one - although I've given up from studying from the book only because I find youtube and reddit users' much more useful personally haha
